122-556: The Mongolian-Manchurian grassland ( Chinese : 蒙古高原草原-内蒙古草原-东北草原 ) covers an area of 887,300 square kilometers (342,600 sq mi). This temperate grasslands, savannas, and shrublands ecoregion of the Palearctic realm forms a large crescent around the Gobi Desert , extending across central and eastern Mongolia into the eastern portion of Inner Mongolia and eastern and central Manchuria , and then southwest across

244-469: A nucleus that has a vowel (which can be a monophthong , diphthong , or even a triphthong in certain varieties), preceded by an onset (a single consonant , or consonant + glide ; a zero onset is also possible), and followed (optionally) by a coda consonant; a syllable also carries a tone . There are some instances where a vowel is not used as a nucleus. An example of this is in Cantonese, where

366-457: A subject–verb–object word order , and like many other languages of East Asia, makes frequent use of the topic–comment construction to form sentences. Chinese also has an extensive system of classifiers and measure words , another trait shared with neighboring languages such as Japanese and Korean. Other notable grammatical features common to all the spoken varieties of Chinese include the use of serial verb construction , pronoun dropping , and

488-561: A writing system , built huge pyramids and temples , had a complex calendar , and developed the concept of zero around 400 CE. The first recorded European references to North America are in Norse sagas where it is referred to as Vinland . The earliest verifiable instance of pre-Columbian trans-oceanic contact by any European culture with the North America mainland has been dated to around 1000 CE. The site , situated at

610-510: A Chinese character is the morpheme, as characters represent the smallest grammatical units with individual meanings in the Chinese language. Estimates of the total number of Chinese words and lexicalized phrases vary greatly. The Hanyu Da Zidian , a compendium of Chinese characters, includes 54,678 head entries for characters, including oracle bone versions. The Zhonghua Zihai (1994) contains 85,568 head entries for character definitions and

732-599: A Shanghai resident may speak both Standard Chinese and Shanghainese ; if they grew up elsewhere, they are also likely fluent in the dialect of their home region. In addition to Standard Chinese, a majority of Taiwanese people also speak Taiwanese Hokkien (also called 台語 ; 'Taiwanese' ), Hakka , or an Austronesian language . A speaker in Taiwan may mix pronunciations and vocabulary from Standard Chinese and other languages of Taiwan in everyday speech. In part due to traditional cultural ties with Guangdong , Cantonese

854-462: A central variety (i.e. prestige variety, such as Standard Mandarin), as the issue requires some careful handling when mutual intelligibility is inconsistent with language identity. The Chinese government's official Chinese designation for the major branches of Chinese is 方言 ; fāngyán ; 'regional speech', whereas the more closely related varieties within these are called 地点方言 ; 地點方言 ; dìdiǎn fāngyán ; 'local speech'. Because of

The dominant flora consists of medium to tall grasslands, dominated by feather grass ( Stipa baicalensis , S. capillata , and S. grandis ), sheep's fescue ( Festuca ovina ), Aneurolepidium chinense , Filifolium sibiricuman , and Cleistogenes sqarrosa . The drier regions surrounding

1098-615: A compromise between the pronunciations of different regions. The royal courts of the Ming and early Qing dynasties operated using a koiné language known as Guanhua , based on the Nanjing dialect of Mandarin. Standard Chinese is an official language of both the People's Republic of China and the Republic of China (Taiwan), one of the four official languages of Singapore , and one of

1220-714: A corresponding increase in the number of homophones . As an example, the small Langenscheidt Pocket Chinese Dictionary lists six words that are commonly pronounced as shí in Standard Chinese: In modern spoken Mandarin, however, tremendous ambiguity would result if all of these words could be used as-is. The 20th century Yuen Ren Chao poem Lion-Eating Poet in the Stone Den exploits this, consisting of 92 characters all pronounced shi . As such, most of these words have been replaced in speech, if not in writing, with less ambiguous disyllabic compounds. Only

1342-576: A millennium. The Four Commanderies of Han were established in northern Korea in the 1st century BCE but disintegrated in the following centuries. Chinese Buddhism spread over East Asia between the 2nd and 5th centuries CE, and with it the study of scriptures and literature in Literary Chinese. Later, strong central governments modeled on Chinese institutions were established in Korea, Japan, and Vietnam, with Literary Chinese serving as

1464-597: A part of Denmark) and Mexico classified as Latin American). It is unknown with certainty how and when first human populations first reached North America. People were known to live in the Americas at least 20,000 years ago, but various evidence points to possibly earlier dates. The Paleo-Indian period in North America followed the Last Glacial Period, and lasted until about 10,000 years ago when

1586-664: A period of mountain building called the Laramide orogeny , between 80 and 55 mya. The formation of the Isthmus of Panama that connected the continent to South America arguably occurred approximately 12 to 15 mya, and the Great Lakes (as well as many other northern freshwater lakes and rivers) were carved by receding glaciers about 10,000 years ago. North America is the source of much of what humanity knows about geologic time periods. The geographic area that would later become

1708-590: A powerful earthquake killed seven people in 2009. Volcanic eruptions are common in the region. In 1968, the Arenal Volcano , in Costa Rica, erupted and killed 87 people. Fertile soils from weathered volcanic lavas have made it possible to sustain dense populations in agriculturally productive highland areas. Central America has many mountain ranges ; the longest are the Sierra Madre de Chiapas ,

1830-542: A secure reconstruction of Proto-Sino-Tibetan, the higher-level structure of the family remains unclear. A top-level branching into Chinese and Tibeto-Burman languages is often assumed, but has not been convincingly demonstrated. The first written records appeared over 3,000 years ago during the Shang dynasty . As the language evolved over this period, the various local varieties became mutually unintelligible. In reaction, central governments have repeatedly sought to promulgate

1952-508: A similar way to the use of Latin and Ancient Greek roots in European languages. Many new compounds, or new meanings for old phrases, were created in the late 19th and early 20th centuries to name Western concepts and artifacts. These coinages, written in shared Chinese characters, have then been borrowed freely between languages. They have even been accepted into Chinese, a language usually resistant to loanwords, because their foreign origin

2074-678: A single language. However, their lack of mutual intelligibility means they are sometimes considered to be separate languages in a family . Investigation of the historical relationships among the varieties of Chinese is ongoing. Currently, most classifications posit 7 to 13 main regional groups based on phonetic developments from Middle Chinese , of which the most spoken by far is Mandarin with 66%, or around 800 million speakers, followed by Min (75 million, e.g. Southern Min ), Wu (74 million, e.g. Shanghainese ), and Yue (68 million, e.g. Cantonese ). These branches are unintelligible to each other, and many of their subgroups are unintelligible with

2196-631: A unified standard. The earliest examples of Old Chinese are divinatory inscriptions on oracle bones dated to c.  1250 BCE , during the Late Shang . The next attested stage came from inscriptions on bronze artifacts dating to the Western Zhou period (1046–771 BCE), the Classic of Poetry and portions of the Book of Documents and I Ching . Scholars have attempted to reconstruct

2318-575: A variety of Yue from a small coastal area around Taishan, Guangdong . In parts of South China, the dialect of a major city may be only marginally intelligible to its neighbors. For example, Wuzhou and Taishan are located approximately 260 km (160 mi) and 190 km (120 mi) away from Guangzhou respectively, but the Yue variety spoken in Wuzhou is more similar to the Guangzhou dialect than

2440-417: A variety of habitats not restricted solely to the open steppe. Many are programmed to traverse vast distances in extreme weather and terrain by running, digging, and/or flying. In the winter the grass becomes dry and very flammable, making wildfires more common. Grass recovers quickly from the fire, but trees do not. This partially explains the absence of trees in the area. There are also seasonal droughts in

2562-540: A variety of reactions, including curiosity, trading, cooperation, resignation, and resistance. The indigenous population declined substantially following European arrival, primarily due to the introduction of Eurasian diseases, such as smallpox , to which the indigenous peoples lacked immunity, and because of violent conflicts with Europeans. Indigenous culture changed significantly and their affiliation with political and cultural groups also changed. Several linguistic groups died out , and others changed quite quickly. On

2684-714: A wide variety of traditional Mongolian songs. The Mongolian-Manchurian grassland faces threat from human expansion, though in most of its eastern area, it has not been altered by agriculture as much as its reaches in its western area, or similar grasslands in North America . 5.09% of the ecoregion is in protected areas. Protected areas include: 47°N 119°E  /  47°N 119°E  / 47; 119 Chinese language Chinese ( simplified Chinese : 汉语 ; traditional Chinese : 漢語 ; pinyin : Hànyǔ ; lit. ' Han language' or 中文 ; Zhōngwén ; 'Chinese writing')

2806-602: Is Taishanese. Wuzhou is located directly upstream from Guangzhou on the Pearl River , whereas Taishan is to Guangzhou's southwest, with the two cities separated by several river valleys. In parts of Fujian , the speech of some neighbouring counties or villages is mutually unintelligible. Local varieties of Chinese are conventionally classified into seven dialect groups, largely based on the different evolution of Middle Chinese voiced initials: Proportions of first-language speakers The classification of Li Rong , which

2928-883: Is a continent in the Northern and Western Hemispheres . North America is bordered to the north by the Arctic Ocean , to the east by the Atlantic Ocean , to the southeast by South America and the Caribbean Sea , and to the west and south by the Pacific Ocean . The region includes the Bahamas , Bermuda , Canada , the Caribbean , Central America , Clipperton Island , Greenland , Mexico , Saint Pierre and Miquelon , Turks and Caicos Islands , and

3050-709: Is a group of languages spoken natively by the ethnic Han Chinese majority and many minority ethnic groups in China , as well as by various communities of the Chinese diaspora . Approximately 1.35 billion people, or 17% of the global population, speak a variety of Chinese as their first language . Chinese languages form the Sinitic branch of the Sino-Tibetan language family. The spoken varieties of Chinese are usually considered by native speakers to be dialects of

3172-665: Is a very large continent that extends from north of the Arctic Circle to south of the Tropic of Cancer . Greenland, along with the Canadian Shield , is tundra with average temperatures ranging from 10 to 20 °C (50 to 68 °F), but central Greenland is composed of a very large ice sheet. This tundra radiates throughout Canada, but its border ends near the Rocky Mountains (but still contains Alaska) and at

3294-524: Is an ancient craton which forms the geologic core of North America; it formed between 1.5 and 1.0 billion years ago during the Proterozoic eon. The Canadian Shield is the largest exposure of this craton. From the Late Paleozoic to Early Mesozoic eras, North America was joined with the other modern-day continents as part of the supercontinent Pangaea , with Eurasia to its east. One of

3416-490: Is called either 华语 ; 華語 ; Huáyǔ or 汉语 ; 漢語 ; Hànyǔ ). Standard Chinese is based on the Beijing dialect of Mandarin. The governments of both China and Taiwan intend for speakers of all Chinese speech varieties to use it as a common language of communication. Therefore, it is used in government agencies, in the media, and as a language of instruction in schools. Diglossia is common among Chinese speakers. For example,

3538-546: Is in present-day Panama at the Darien Gap on the Colombia -Panama border, placing almost all of Panama within North America. Alternatively, some geologists physiographically locate its southern limit at the Isthmus of Tehuantepec , Mexico, with Central America extending southeastward to South America from this point. The Caribbean islands, or West Indies, are considered part of North America. The continental coastline

3660-648: Is long and irregular. The Gulf of Mexico is the largest body of water indenting the continent, followed by Hudson Bay . Others include the Gulf of Saint Lawrence and the Gulf of California . Before the Central American isthmus formed, the region had been underwater. The islands of the West Indies delineate a submerged former land bridge , which had connected North and South America via what are now Florida and Venezuela . There are several islands off

3782-603: Is often described as a 'monosyllabic' language. However, this is only partially correct. It is largely accurate when describing Old and Middle Chinese; in Classical Chinese, around 90% of words consist of a single character that corresponds one-to-one with a morpheme , the smallest unit of meaning in a language. In modern varieties, it usually remains the case that morphemes are monosyllabic—in contrast, English has many multi-syllable morphemes, both bound and free , such as 'seven', 'elephant', 'para-' and '-able'. Some of

3904-445: Is only about an eighth as many as English. All varieties of spoken Chinese use tones to distinguish words. A few dialects of north China may have as few as three tones, while some dialects in south China have up to 6 or 12 tones, depending on how one counts. One exception from this is Shanghainese which has reduced the set of tones to a two-toned pitch accent system much like modern Japanese. A very common example used to illustrate

4026-561: Is part of North America geographically. In a geologic sense, Bermuda is not part of the Americas, but an oceanic island that was formed on the fissure of the Mid-Atlantic Ridge over 100 million years ago (mya). The nearest landmass to it is Cape Hatteras , North Carolina . However, Bermuda is often thought of as part of North America, especially given its historical, political and cultural ties to Virginia and other parts of

4148-668: Is specifically meant. However, when one of the above words forms part of a compound, the disambiguating syllable is generally dropped and the resulting word is still disyllabic. For example, 石 ; shí alone, and not 石头 ; 石頭 ; shítou , appears in compounds as meaning 'stone' such as 石膏 ; shígāo ; 'plaster', 石灰 ; shíhuī ; 'lime', 石窟 ; shíkū ; 'grotto', 石英 ; 'quartz', and 石油 ; shíyóu ; 'petroleum'. Although many single-syllable morphemes ( 字 ; zì ) can stand alone as individual words, they more often than not form multi-syllable compounds known as 词 ; 詞 ; cí , which more closely resembles

4270-707: Is the Morrison Formation of the western U.S. Canada is geologically one of the oldest regions in the world, with more than half of the region consisting of Precambrian rocks that have been above sea level since the beginning of the Palaeozoic era. Canada's mineral resources are diverse and extensive. Across the Canadian Shield and in the north there are large iron, nickel, zinc , copper, gold, lead, molybdenum , and uranium reserves. Large diamond concentrations have been recently developed in

Stretching from the borders of the humid continental and subtropical climates, and going west to the Sierra Nevada , south to the southern tip of Durango , north to the border with tundra climate, the steppe / desert climates are

4514-489: Is the largest reference work based purely on character and its literary variants. The CC-CEDICT project (2010) contains 97,404 contemporary entries including idioms, technology terms, and names of political figures, businesses, and products. The 2009 version of the Webster's Digital Chinese Dictionary (WDCD), based on CC-CEDICT, contains over 84,000 entries. The most comprehensive pure linguistic Chinese-language dictionary,

4636-501: Is used as an everyday language in Hong Kong and Macau . The designation of various Chinese branches remains controversial. Some linguists and most ordinary Chinese people consider all the spoken varieties as one single language, as speakers share a common national identity and a common written form. Others instead argue that it is inappropriate to refer to major branches of Chinese such as Mandarin, Wu, and so on as "dialects" because

4758-500: Is used in education, media, formal speech, and everyday life—though Mandarin is increasingly taught in schools due to the mainland's growing influence. Historically, the Chinese language has spread to its neighbors through a variety of means. Northern Vietnam was incorporated into the Han dynasty (202 BCE – 220 CE) in 111 BCE, marking the beginning of a period of Chinese control that ran almost continuously for

4880-552: Is used in the Language Atlas of China (1987), distinguishes three further groups: Some varieties remain unclassified, including the Danzhou dialect on Hainan , Waxianghua spoken in western Hunan , and Shaozhou Tuhua spoken in northern Guangdong . Standard Chinese is the standard language of China (where it is called 普通话 ; pǔtōnghuà ) and Taiwan, and one of the four official languages of Singapore (where it

5002-428: Is very complex, with a large number of consonants and vowels, but they are probably not all distinguished in any single dialect. Most linguists now believe it represents a diasystem encompassing 6th-century northern and southern standards for reading the classics. The complex relationship between spoken and written Chinese is an example of diglossia : as spoken, Chinese varieties have evolved at different rates, while

5124-753: The Qieyun rime dictionary (601 CE), and a late period in the 10th century, reflected by rhyme tables such as the Yunjing constructed by ancient Chinese philologists as a guide to the Qieyun system. These works define phonological categories but with little hint of what sounds they represent. Linguists have identified these sounds by comparing the categories with pronunciations in modern varieties of Chinese , borrowed Chinese words in Japanese, Vietnamese, and Korean, and transcription evidence. The resulting system

5246-454: The Age of Discovery and the early modern period . Present-day cultural and ethnic patterns reflect interactions between European colonists, indigenous peoples , enslaved Africans , immigrants from Europe, Asia, and descendants of these respective groups. Europe's colonization in North America led to most North Americans speaking European languages, such as English , Spanish , and French , and

5368-519: The Archaic period began. The classic stage followed the Archaic period, and lasted from approximately the 6th to 13th centuries. Beginning in 1000 AD, the Norse were the first Europeans to begin exploring and ultimately colonizing areas of North America. In 1492, the exploratory voyages of Christopher Columbus led to a transatlantic exchange , including migrations of European settlers during

5490-567: The Bering Strait during the Early-Middle Holocene . Prior to the arrival of European explorers and colonists in North America, the natives of North America were divided into many different polities, ranging from small bands of a few families to large empires. They lived in several culture areas , which roughly correspond to geographic and biological zones that defined the representative cultures and lifestyles of

In the U.S., they include New England , the Mid-Atlantic , South Atlantic states , East North Central states , West North Central states , East South Central states , West South Central states , Mountain states , and Pacific states . The Great Lakes region and the Pacific Northwest include areas in both Canada and

5734-913: The Caribbean Plate , whereas the Juan de Fuca Plate and Cocos Plate border the North American Plate on its western frontier. The continent can be divided into four great regions (each of which contains many subregions): the Great Plains stretching from the Gulf of Mexico to the Canadian Arctic ; the geologically young, mountainous west, including the Rocky Mountains , the Great Basin , California , and Alaska ;

5856-568: The Cordillera Isabelia , and the Cordillera de Talamanca . Between the mountain ranges lie fertile valleys that are suitable for the people; in fact, most of the population of Honduras, Costa Rica, and Guatemala live in valleys. Valleys are also suitable for the production of coffee, beans, and other crops. The indigenous peoples of the Americas have many creation myths , based on which they assert that they have been present on

5978-465: The East Coast to eastern North Dakota , and stretching down to Kansas , is the humid continental climate featuring intense seasons, with a large amount of annual precipitation, with places like New York City averaging 50 in (1,300 mm). Starting at the southern border of the humid continental climate and stretching to the Gulf of Mexico (whilst encompassing the eastern half of Texas)

6100-620: The Inuit of the high Arctic arrived in North America much later than other native groups, evidenced by the disappearance of Dorset culture artifacts from the archaeological record and their replacement by the Thule people . During the thousands of years of native habitation on the continent, cultures changed and shifted. One of the oldest yet discovered is the Clovis culture (c. 9550–9050 BCE) in modern New Mexico . Later groups include

6222-533: The Korean , Japanese and Vietnamese languages, and today comprise over half of their vocabularies. This massive influx led to changes in the phonological structure of the languages, contributing to the development of moraic structure in Japanese and the disruption of vowel harmony in Korean. Borrowed Chinese morphemes have been used extensively in all these languages to coin compound words for new concepts, in

6344-451: The May Fourth Movement beginning in 1919. After the fall of the Northern Song dynasty and subsequent reign of the Jurchen Jin and Mongol Yuan dynasties in northern China, a common speech (now called Old Mandarin ) developed based on the dialects of the North China Plain around the capital. The 1324 Zhongyuan Yinyun was a dictionary that codified the rhyming conventions of new sanqu verse form in this language. Together with

6466-478: The Mississippian culture and related Mound building cultures, found in the Mississippi River valley and the Pueblo culture of what is now the Four Corners . The more southern cultural groups of North America were responsible for the domestication of many common crops now used around the world, such as tomatoes, squash , and maize . As a result of the development of agriculture in the south, many other cultural advances were made there. The Mayans developed

6588-497: The National Language Unification Commission finally settled on the Beijing dialect in 1932. The People's Republic founded in 1949 retained this standard but renamed it 普通话 ; 普通話 ; pǔtōnghuà ; 'common speech'. The national language is now used in education, the media, and formal situations in both mainland China and Taiwan. In Hong Kong and Macau , Cantonese is the dominant spoken language due to cultural influence from Guangdong immigrants and colonial-era policies, and

6710-426: The North China Plain . To the northeast and north, the Selenge-Orkhon and Daurian forest steppes form a transition zone between the grassland and the forests of Siberia to the north. On the east and southeast, the grasslands transition to temperate broadleaf and mixed forests , including the Manchurian mixed forests , Northeast China Plain deciduous forests , and Central China loess plateau mixed forests . On

6832-403: The United States . North America covers an area of about 24,709,000 square kilometers (9,540,000 square miles), representing approximately 16.5% of the Earth 's land area and 4.8% of its total surface area. It is the third-largest continent by size after Asia and Africa , and the fourth-largest continent by population after Asia, Africa, and Europe . As of 2021 , North America's population

6954-420: The first official name given to Mexico. North America includes several regions and subregions, each of which have their own respective cultural, economic, and geographic regions. Economic regions include several regions formalized in 20th- and 21st-century trade agreements, including NAFTA between Canada , Mexico , and the United States , and CAFTA between Central America , the Dominican Republic , and

7076-423: The oracle bone inscriptions created during the Shang dynasty c.  1250 BCE . The phonetic categories of Old Chinese can be reconstructed from the rhymes of ancient poetry. During the Northern and Southern period , Middle Chinese went through several sound changes and split into several varieties following prolonged geographic and political separation. The Qieyun , a rime dictionary , recorded

Although many of the finer details remain unclear, most scholars agree that Old Chinese differs from Middle Chinese in lacking retroflex and palatal obstruents but having initial consonant clusters of some sort, and in having voiceless nasals and liquids. Most recent reconstructions also describe an atonal language with consonant clusters at

7320-641: The 12-volume Hanyu Da Cidian , records more than 23,000 head Chinese characters and gives over 370,000 definitions. The 1999 revised Cihai , a multi-volume encyclopedic dictionary reference work, gives 122,836 vocabulary entry definitions under 19,485 Chinese characters, including proper names, phrases, and common zoological, geographical, sociological, scientific, and technical terms.

The largest, and best known, is Sudbury , Ontario. Sudbury is an exception to the normal process of forming minerals in the Shield since there is significant evidence that the Sudbury Basin is an ancient meteorite impact crater . The nearby, but less-known Temagami Magnetic Anomaly has striking similarities to

7686-478: The Caribbean islands. France took the western half of Hispaniola and developed Saint-Domingue as a cane sugar producing colony worked by black slave labor. Britain took Barbados and Jamaica , and the Dutch and Danes took islands previously claimed by Spain. Britain did not begin settling on the North American mainland until a hundred years after the first Spanish settlements, since it sought first to control nearby Ireland .

English words of Chinese origin include tea from Hokkien 茶 ( tê ), dim sum from Cantonese 點心 ( dim2 sam1 ), and kumquat from Cantonese 金橘 ( gam1 gwat1 ). The sinologist Jerry Norman has estimated that there are hundreds of mutually unintelligible varieties of Chinese. These varieties form a dialect continuum , in which differences in speech generally become more pronounced as distances increase, though

8174-419: The North America's southeastern coast, Spanish explorer Juan Ponce de León , who had accompanied Columbus's second voyage, visited and named in 1513 La Florida . As the colonial period unfolded, Spain, England, and France appropriated and claimed extensive territories in North America eastern and southern coastlines. Spain established permanent settlements on the Caribbean islands of Hispaniola and Cuba in

North America is the third-largest continent by area after Asia and Africa . North America's only land connection to South America

8540-429: The United States has been the source of more varieties of dinosaurs than any other modern country. According to paleontologist Peter Dodson, this is primarily due to stratigraphy, climate and geography, human resources, and history. Much of the Mesozoic Era is represented by exposed outcrops in the many arid regions of the continent. The most significant Late Jurassic dinosaur-bearing fossil deposit in North America

France , Italy , Portugal , Spain , Romania , Greece , and the countries of Latin America use a six-continent model , with the Americas viewed as a single continent and North America designating a subcontinent comprising Canada , the United States , Mexico, and Saint Pierre and Miquelon (politically part of France), and often including Greenland and Bermuda . North America has historically been known by other names, including Spanish North America, New Spain , and América Septentrional,

8784-697: The United States. North America is divided linguistically and culturally into two primary regions, Anglo-America and Latin America . Anglo-America includes most of North America, Belize , and Caribbean islands with English -speaking populations. There are also regions, including Louisiana and Quebec , with large Francophone populations; in Quebec , French is the official language. .

Greenland , a self-governing Danish island, and the world's largest , is on the same tectonic plate (the North American Plate ) and

9272-599: The continent. The vast majority of North America is on the North American Plate. Parts of western Mexico, including Baja California, and of California , including the cities of San Diego , Los Angeles , and Santa Cruz , lie on the eastern edge of the Pacific Plate , with the two plates meeting along the San Andreas Fault . The southernmost portion of the continent and much of the West Indies lie on

9394-659: The cordillera, while the major islands of Hawaii consist of Neogene volcanics erupted over a hot spot . Central America is geologically active with volcanic eruptions and earthquakes occurring from time to time. In 1976 Guatemala was hit by a major earthquake , killing 23,000 people; Managua, the capital of Nicaragua, was devastated by earthquakes in 1931 and 1972, the last one killing about 5,000 people; three earthquakes devastated El Salvador, one in 1986 and two in 2001; one earthquake devastated northern and central Costa Rica in 2009, killing at least 34 people; in Honduras

9516-685: The cultures of the region commonly reflect Western traditions . However, relatively small parts of North America in Canada, the United States, Mexico, and Central America have indigenous populations that continue adhering to their respective pre-European colonial cultural and linguistic traditions. The Americas were named after the Italian explorer Amerigo Vespucci by German cartographers Martin Waldseemüller and Matthias Ringmann . Vespucci explored South America between 1497 and 1502, and

9638-399: The different spoken dialects varies, but in general, there has been a tendency to a reduction in sounds from Middle Chinese. The Mandarin dialects in particular have experienced a dramatic decrease in sounds and so have far more polysyllabic words than most other spoken varieties. The total number of syllables in some varieties is therefore only about a thousand, including tonal variation, which

9760-484: The difficulties involved in determining the difference between language and dialect, other terms have been proposed. These include topolect , lect , vernacular , regional , and variety . Syllables in the Chinese languages have some unique characteristics. They are tightly related to the morphology and also to the characters of the writing system, and phonologically they are structured according to fixed rules. The structure of each syllable consists of

9882-447: The driest in the U.S. Highland climates cut from north to south of the continent, where subtropical or temperate climates occur just below the tropics, as in central Mexico and Guatemala . Tropical climates appear in the island regions and in the subcontinent's bottleneck, found in countries and states bathed by the Caribbean Sea or to the south of the Gulf of Mexico and the Pacific Ocean . Precipitation patterns vary across

10004-470: The end of the Canadian Shield, near the Great Lakes . Climate west of the Cascade Range is described as being temperate weather with average precipitation 20 inches (510 millimeters). Climate in coastal California is described to be Mediterranean , with average temperatures in cities like San Francisco ranging from 57 to 70 °F (14 to 21 °C) over the course of the year. Stretching from

10126-576: The end of the syllable, developing into tone distinctions in Middle Chinese. Several derivational affixes have also been identified, but the language lacks inflection , and indicated grammatical relationships using word order and grammatical particles . Middle Chinese was the language used during Northern and Southern dynasties and the Sui , Tang , and Song dynasties (6th–10th centuries CE). It can be divided into an early period, reflected by

10248-562: The first American inhabitants sailed from Beringia some 13,000 years ago, with widespread habitation of the Americas during the end of the Last Glacial Period , in what is known as the Late Glacial Maximum , around 12,500 years ago. The oldest petroglyphs in North America date from 15,000 to 10,000 years before present. Genetic research and anthropology indicate additional waves of migration from Asia via

10370-413: The first one, 十 , normally appears in monosyllabic form in spoken Mandarin; the rest are normally used in the polysyllabic forms of respectively. In each, the homophone was disambiguated by the addition of another morpheme, typically either a near-synonym or some sort of generic word (e.g. 'head', 'thing'), the purpose of which is to indicate which of the possible meanings of the other, homophonic syllable

10492-491: The form of a word), to indicate a word's function within a sentence. In other words, Chinese has very few grammatical inflections —it possesses no tenses , no voices , no grammatical number , and only a few articles . They make heavy use of grammatical particles to indicate aspect and mood . In Mandarin, this involves the use of particles such as 了 ; le ; ' PFV ', 还 ; 還 ; hái ; 'still', and 已经 ; 已經 ; yǐjīng ; 'already'. Chinese has

10614-911: The geographic center of either the 50 states, the conterminous United States, or the North American continent." Nonetheless, there is a 4.6-meter (15 ft) field stone obelisk in Rugby claiming to mark the center. The North American continental pole of inaccessibility is located 1,650 km (1,030 mi) from the nearest coastline, between Allen and Kyle, South Dakota at 43°22′N 101°58′W  /  43.36°N 101.97°W  / 43.36; -101.97  ( Pole of Inaccessibility North America ) . Canada can be divided into roughly seven physiographic divisions: The lower 48 U.S. states can be divided into roughly eight physiographic divisions: Mexico can be divided into roughly fifteen physiographic divisions: North America

10736-618: The government of the People's Republic of China, with Singapore officially adopting them in 1976. Traditional characters are used in Taiwan, Hong Kong, Macau, and among Chinese-speaking communities overseas . Linguists classify all varieties of Chinese as part of the Sino-Tibetan language family , together with Burmese , Tibetan and many other languages spoken in the Himalayas and the Southeast Asian Massif . Although

10858-478: The grasslands, typically occurring during summer. The majority of people in the steppe are Mongolian nomads. Families in the Mongolian steppe live in "gers" which are a type of large portable tent. Mongolians are also master horse riders so many families own many horses that roam the steppe. The people in the steppe use the animals there for their food and drink. They also have a very prominent musical culture with

10980-419: The indigenous people who lived there, including the bison hunters of the Great Plains and the farmers of Mesoamerica . Native groups also are classified by their language families , which included Athapascan and Uto-Aztecan languages. Indigenous peoples with similar languages did not always share the same material culture , however, and were not necessarily always allies. Anthropologists speculate that

11102-468: The land since its creation, but there is no evidence that humans evolved there. The specifics of the initial settlement of the Americas by ancient Asians are subject to ongoing research and discussion. The traditional theory has been that hunters entered the Bering Land Bridge between eastern Siberia and present-day Alaska from 27,000 to 14,000 years ago. A growing viewpoint is that

11224-586: The language of administration and scholarship, a position it would retain until the late 19th century in Korea and (to a lesser extent) Japan, and the early 20th century in Vietnam. Scholars from different lands could communicate, albeit only in writing, using Literary Chinese. Although they used Chinese solely for written communication, each country had its own tradition of reading texts aloud using what are known as Sino-Xenic pronunciations . Chinese words with these pronunciations were also extensively imported into

11346-528: The late 19th century. Today Japanese is written with a composite script using both Chinese characters called kanji , and kana. Korean is written exclusively with hangul in North Korea, although knowledge of the supplementary Chinese characters called hanja is still required, and hanja are increasingly rarely used in South Korea. As a result of its historical colonization by France, Vietnamese now uses

11468-714: The mainland in Mexico. With local indigenous allies, the Spanish conquered the Aztec empire in central Mexico in 1521. Spain then established permanent cities in Mexico, Central America, and Spanish South America in the sixteenth century. Once Spaniards conquered the high civilization of the Aztecs and Incas, the Caribbean was a backwater of the Spanish empire. Other European powers began to intrude on areas claimed by Spain, including

11590-927: The middle into the main range of the Rockies and the coast ranges in California , Oregon , Washington , and British Columbia , with the Great Basin—a lower area containing smaller ranges and low-lying deserts—in between. The highest peak is Denali in Alaska. The U.S. Geographical Survey (USGS) states that the geographic center of North America is "6 miles [10 km] west of Balta, Pierce County, North Dakota " at about 48°10′N 100°10′W  /  48.167°N 100.167°W  / 48.167; -100.167 , about 24 kilometers (15 mi) from Rugby, North Dakota . The USGS further states that "No marked or monumented point has been established by any government agency as

11712-455: The more conservative modern varieties, usually found in the south, have largely monosyllabic words , especially with basic vocabulary. However, most nouns, adjectives, and verbs in modern Mandarin are disyllabic. A significant cause of this is phonetic erosion : sound changes over time have steadily reduced the number of possible syllables in the language's inventory. In modern Mandarin, there are only around 1,200 possible syllables, including

11834-425: The mutual unintelligibility between them is too great. However, calling major Chinese branches "languages" would also be wrong under the same criterion, since a branch such as Wu, itself contains many mutually unintelligible varieties, and could not be properly called a single language. There are also viewpoints pointing out that linguists often ignore mutual intelligibility when varieties share intelligibility with

11956-454: The name America to North America. In 1538, Gerardus Mercator used the term America on his world map of the entire Western Hemisphere . On his subsequent 1569 map , Mercator called North America "America or New India" ( America sive India Nova ). The Spanish Empire called its territories in North and South America "Las Indias", and the name given to the state body that oversaw the region

12078-583: The nasal sonorant consonants /m/ and /ŋ/ can stand alone as their own syllable. In Mandarin much more than in other spoken varieties, most syllables tend to be open syllables, meaning they have no coda (assuming that a final glide is not analyzed as a coda), but syllables that do have codas are restricted to nasals /m/ , /n/ , /ŋ/ , the retroflex approximant /ɻ/ , and voiceless stops /p/ , /t/ , /k/ , or /ʔ/ . Some varieties allow most of these codas, whereas others, such as Standard Chinese, are limited to only /n/ , /ŋ/ , and /ɻ/ . The number of sounds in

12200-493: The northernmost countries and territories of North America: the U.S., Bermuda , Canada, Greenland, and St. Pierre and Miquelon. Although the term does not refer to a unified region, Middle America includes Mexico, Central America, and the Caribbean. North America's largest countries by land area are Canada and the U.S., both of which have well-defined and recognized subregions. In Canada, these include (from east to west) Atlantic Canada , Central Canada , Canadian Prairies ,

12322-440: The northernmost extent of the island named Newfoundland , has provided unmistakable evidence of Norse settlement. Norse explorer Leif Erikson (c. 970–1020 CE) is thought to have visited the area. Erikson was the first European to make landfall on the continent (excluding Greenland). The Mayan culture was still present in southern Mexico and Guatemala when the Spanish conquistadors arrived, but political dominance in

12444-538: The other varieties within the same branch (e.g. Southern Min). There are, however, transitional areas where varieties from different branches share enough features for some limited intelligibility, including New Xiang with Southwestern Mandarin , Xuanzhou Wu Chinese with Lower Yangtze Mandarin , Jin with Central Plains Mandarin and certain divergent dialects of Hakka with Gan . All varieties of Chinese are tonal at least to some degree, and are largely analytic . The earliest attested written Chinese consists of

12566-605: The raised but relatively flat plateau of the Canadian Shield in the northeast; and the varied eastern region, which includes the Appalachian Mountains, the coastal plain along the Atlantic seaboard, and the Florida peninsula. Mexico, with its long plateaus and cordilleras , falls largely in the western region, although the eastern coastal plain does extend south along the Gulf. The western mountains are split in

12688-471: The rate of change varies immensely. Generally, mountainous South China exhibits more linguistic diversity than the North China Plain . Until the late 20th century, Chinese emigrants to Southeast Asia and North America came from southeast coastal areas, where Min, Hakka, and Yue dialects were spoken. Specifically, most Chinese immigrants to North America until the mid-20th century spoke Taishanese ,

12810-500: The region, and as such rainforest , monsoon , and savanna types can be found, with rains and high temperatures throughout the year. Notable North American fauna include the bison , black bear , jaguar , cougar , prairie dog , turkey , pronghorn , raccoon , coyote , and monarch butterfly . Notable plants that were domesticated in North America include tobacco , maize , squash , tomato , sunflower , blueberry , avocado , cotton , chile pepper , and vanilla . Laurentia

12932-552: The related subject dropping . Although the grammars of the spoken varieties share many traits, they do possess differences. The entire Chinese character corpus since antiquity comprises well over 50,000 characters, of which only roughly 10,000 are in use and only about 3,000 are frequently used in Chinese media and newspapers. However, Chinese characters should not be confused with Chinese words. Because most Chinese words are made up of two or more characters, there are many more Chinese words than characters. A more accurate equivalent for

13054-509: The relationship was first proposed in the early 19th century and is now broadly accepted, reconstruction of Sino-Tibetan is much less developed than that of families such as Indo-European or Austroasiatic . Difficulties have included the great diversity of the languages, the lack of inflection in many of them, and the effects of language contact. In addition, many of the smaller languages are spoken in mountainous areas that are difficult to reach and are often also sensitive border zones. Without

13176-487: The results of the formation of Pangaea was the Appalachian Mountains , which formed some 480 mya, making it among the oldest mountain ranges in the world. When Pangaea began to rift around 200 mya, North America became part of Laurasia , before it separated from Eurasia as its own continent during the mid- Cretaceous period. The Rockies and other western mountain ranges began forming around this time from

13298-517: The six official languages of the United Nations . Standard Chinese is based on the Beijing dialect of Mandarin and was first officially adopted in the 1930s. The language is written primarily using a logography of Chinese characters , largely shared by readers who may otherwise speak mutually unintelligible varieties. Since the 1950s, the use of simplified characters has been promoted by

13420-561: The slightly later Menggu Ziyun , this dictionary describes a language with many of the features characteristic of modern Mandarin dialects. Up to the early 20th century, most Chinese people only spoke their local variety. Thus, as a practical measure, officials of the Ming and Qing dynasties carried out the administration of the empire using a common language based on Mandarin varieties , known as 官话 ; 官話 ; Guānhuà ; 'language of officials'. For most of this period, this language

13542-798: The southwest, the grasslands extend to the Yellow River , across which is the Ordos Plateau steppe . It lies between the Altai Mountains in the west and the Greater Khingan Region in the east. The climate is hypercontinental sub- humid or semi-arid , with the Köppen classifications BSk or in the extreme east, Dwa or Dwb . The region features warm summers with decreasing rainfall from east to west, alongside frigid, extremely dry winters. Being relatively dry, from

13664-623: The tonal distinctions, compared with about 5,000 in Vietnamese (still a largely monosyllabic language), and over 8,000 in English. Most modern varieties tend to form new words through polysyllabic compounds . In some cases, monosyllabic words have become disyllabic formed from different characters without the use of compounding, as in 窟窿 ; kūlong from 孔 ; kǒng ; this is especially common in Jin varieties. This phonological collapse has led to

13786-547: The traditional Western notion of a word. A Chinese cí can consist of more than one character–morpheme, usually two, but there can be three or more. Examples of Chinese words of more than two syllables include 汉堡包 ; 漢堡包 ; hànbǎobāo ; 'hamburger', 守门员 ; 守門員 ; shǒuményuán ; 'goalkeeper', and 电子邮件 ; 電子郵件 ; diànzǐyóujiàn ; 'e-mail'. All varieties of modern Chinese are analytic languages : they depend on syntax (word order and sentence structure), rather than inflectional morphology (changes in

13908-512: The use of tones in Chinese is the application of the four tones of Standard Chinese, along with the neutral tone, to the syllable ma . The tones are exemplified by the following five Chinese words: In contrast, Standard Cantonese has six tones. Historically, finals that end in a stop consonant were considered to be " checked tones " and thus counted separately for a total of nine tones. However, they are considered to be duplicates in modern linguistics and are no longer counted as such: Chinese

14030-452: The words in newspapers, and 60% of the words in science magazines. Vietnam, Korea, and Japan each developed writing systems for their own languages, initially based on Chinese characters , but later replaced with the hangul alphabet for Korean and supplemented with kana syllabaries for Japanese, while Vietnamese continued to be written with the complex chữ Nôm script. However, these were limited to popular literature until

14152-517: The written language used throughout China changed comparatively little, crystallizing into a prestige form known as Classical or Literary Chinese . Literature written distinctly in the Classical form began to emerge during the Spring and Autumn period . Its use in writing remained nearly universal until the late 19th century, culminating with the widespread adoption of written vernacular Chinese with

14274-453: Was a koiné based on dialects spoken in the Nanjing area, though not identical to any single dialect. By the middle of the 19th century, the Beijing dialect had become dominant and was essential for any business with the imperial court. In the 1930s, a standard national language ( 国语 ; 國語 ; Guóyǔ ), was adopted. After much dispute between proponents of northern and southern dialects and an abortive attempt at an artificial pronunciation,

14396-549: Was called the Council of the Indies . The United Nations and its statistics division recognize North America as including three regions: Northern America, Central America , and the Caribbean . "Northern America" is a distinct term from "North America", excluding Central America, which itself may or may not include Mexico . In the limited context of regional trade agreements, the term is used to reference three nations: Canada,

14518-506: Was estimated as over 592 million people in 23 independent states , or about 7.5% of the world's population. In human geography , the terms "North America" and "North American" can refer to Canada, the United States, Mexico, and Greenland or, alternatively, Canada, Greenland and the US (Mexico being classified as part of Latin America ) or simply Canada and the US (Greenland being classified as either Arctic or European (due to its political status as

14640-485: Was hidden by their written form. Often different compounds for the same concept were in circulation for some time before a winner emerged, and sometimes the final choice differed between countries. The proportion of vocabulary of Chinese origin thus tends to be greater in technical, abstract, or formal language. For example, in Japan, Sino-Japanese words account for about 35% of the words in entertainment magazines, over half

14762-817: Was in Jamestown, Virginia in 1607, followed by additional colonial establishments on the east coast from present-day Georgia in the south to Massachusetts in the north, forming the Thirteen Colonies of British America. The English did not establish settlements north or east of the St. Lawrence Valley in present-day Canada until after the conclusion of the American Revolutionary War . Britain's early settlements in present-day Canada included St. John's, Newfoundland in 1630 and Halifax, Nova Scotia in 1749. The first permanent French settlement

14884-473: Was the first European to suggest that the Americas represented a landmass not then known to the Europeans. In 1507, Waldseemüller published a world map, and placed the word "America" on the continent of present-day South America. The continent north of present-day Mexico was then referred to as Parias. On a 1553 world map published by Petrus Apianus , North America was called "Baccalearum", meaning "realm of
