Acid weathering of feldspar -rich rock, such as granite , in warm climates tends to produce kaolin. Weathering of the same kind of rock under alkaline conditions produces illite . Smectite forms by weathering of igneous rock under alkaline conditions, while gibbsite forms by intense weathering of other clay minerals. There are two types of clay deposits: primary and secondary. Primary clays form as residual deposits in soil and remain at

This produces distinctive textures, such as mudcracks or "popcorn" texture, in clay deposits. Soils containing swelling clay minerals (such as bentonite ) pose a considerable challenge for civil engineering, because swelling clay can break foundations of buildings and ruin road beds. Clay minerals most commonly form by prolonged chemical weathering of silicate-bearing rocks. They can also form locally from hydrothermal activity. Chemical weathering takes place largely by acid hydrolysis due to low concentrations of carbonic acid , dissolved in rainwater or released by plant roots. The acid breaks bonds between aluminium and oxygen, releasing other metal ions and silica (as

However, disaffection with the company also grew during this time and set off
11088-943: The Ganges include the Yamuna and the Kosi ; the latter's extremely low gradient, caused by long-term silt deposition, leads to severe floods and course changes. Major peninsular rivers, whose steeper gradients prevent their waters from flooding, include the Godavari , the Mahanadi , the Kaveri , and the Krishna , which also drain into the Bay of Bengal; and the Narmada and the Tapti , which drain into
11242-555: The Himalayas and the Thar Desert, both of which drive the economically and culturally pivotal summer and winter monsoons . The Himalayas prevent cold Central Asian katabatic winds from blowing in, keeping the bulk of the Indian subcontinent warmer than most locations at similar latitudes. The Thar Desert plays a crucial role in attracting the moisture-laden south-west summer monsoon winds that, between June and October, provide
11396-399: The Himalayas. This had the effect of lowering endemism among India's mammals, which stands at 12.6%, contrasting with 45.8% among reptiles and 55.8% among amphibians. Among endemics are the vulnerable hooded leaf monkey and the threatened Beddome's toad of the Western Ghats. India contains 172 IUCN -designated threatened animal species , or 2.9% of endangered forms. These include
11550-401: The Indian elites, the sultanate largely left its vast non-Muslim subject population to its own laws and customs. By repeatedly repulsing Mongol raiders in the 13th century, the sultanate saved India from the devastation visited on West and Central Asia, setting the scene for centuries of migration of fleeing soldiers, learned men, mystics, traders, artists, and artisans from that region into
11704-463: The Mughals united their far-flung realms through loyalty, expressed through a Persianised culture, to an emperor who had near-divine status. The Mughal state's economic policies, deriving most revenues from agriculture and mandating that taxes be paid in the well-regulated silver currency, caused peasants and artisans to enter larger markets. The relative peace maintained by the empire during much of
11858-557: The advent of independence in 1947, but tempered by the partition of India into two states: India and Pakistan. Vital to India's self-image as an independent nation was its constitution, completed in 1950, which put in place a secular and democratic republic. Per the London Declaration , India retained its membership of the Commonwealth , becoming the first republic within it. Economic liberalisation, which began in
12012-512: The agricultural sector 18.1%. India's foreign exchange remittances of US$ 100 billion in 2022, highest in the world, were contributed to its economy by 32 million Indians working in foreign countries. Major agricultural products include rice, wheat, oilseed, cotton, jute, tea, sugarcane, and potatoes. Major industries include textiles, telecommunications, chemicals, pharmaceuticals, biotechnology, food processing, steel, transport equipment, cement, mining, petroleum, machinery, and software. In 2006,
12166-498: The banking sector, 44th in business sophistication, and 39th in innovation, ahead of several advanced economies. With seven of the world's top 15 information technology outsourcing companies based in India, as of 2009 , the country is viewed as the second-most favourable outsourcing destination after the United States. India is ranked 39th in the Global Innovation Index in 2024. As of 2023 , India's consumer market
12320-608: The beginnings of a nonviolent movement of non-co-operation, of which Mahatma Gandhi would become the leader and enduring symbol. During the 1930s, slow legislative reform was enacted by the British; the Indian National Congress won victories in the resulting elections. The next decade was beset with crises: Indian participation in World War ;II , the Congress's final push for non-co-operation, and an upsurge of Muslim nationalism . All were capped by
12474-496: The benefit which will be derived by a large number of people by the construction of rail line cannot be brushed aside. The Courts are bound to take into consideration the comparative hardship which the people in the region will suffer by stalling the project of great public utility. The cost of the project escalates from day to day and, as pointed out by the Corporation, the extent of the interest and east which will be suffered by
12628-495: The coasts of southern and eastern India. As the empire disintegrated, many among these elites were able to seek and control their own affairs. By the early 18th century, with the lines between commercial and political dominance being increasingly blurred, a number of European trading companies, including the English East India Company , had established coastal outposts. The East India Company's control of
12782-415: The cohesion that makes it plastic. In kaolinite clay, the bonding between plates is provided by a film of water molecules that hydrogen bond the plates together. The bonds are weak enough to allow the plates to slip past each other when the clay is being moulded, but strong enough to hold the plates in place and allow the moulded clay to retain its shape after it is moulded. When the clay is dried, most of
12936-452: The commercialisation of agriculture in the second half of the 19th century was marked by economic setbacks, and many small farmers became dependent on the whims of far-away markets. There was an increase in the number of large-scale famines , and, despite the risks of infrastructure development borne by Indian taxpayers, little industrial employment was generated for Indians. There were also salutary effects: commercial cropping, especially in
13090-625: The contribution of petrochemical and engineering goods to total exports grew from 14% to 42%. India was the world's second-largest textile exporter after China in the 2013 calendar year. Averaging an economic growth rate of 7.5% for several years prior to 2007, India has more than doubled its hourly wage rates during the first decade of the 21st century. Some 431 million Indians have left poverty since 1985; India's middle classes are projected to number around 580 million by 2030. Though ranking 68th in global competitiveness , as of 2010 , India ranks 17th in financial market sophistication, 24th in
13244-630: The cost of increasing economic inequality. India is a nuclear-weapon state , which ranks high in military expenditure . It has disputes over Kashmir with its neighbours, Pakistan and China, unresolved since the mid-20th century. Among the socio-economic challenges India faces are gender inequality , child malnutrition , and rising levels of air pollution . India's land is megadiverse , with four biodiversity hotspots . Its forest cover comprises 21.7% of its area. India's wildlife , which has traditionally been viewed with tolerance in India's culture ,
13398-581: The design and implementation of Vikrant -class aircraft carriers and Arihant -class nuclear submarines . Since the end of the Cold War , India has increased its economic, strategic, and military co-operation with the United States and the European Union . In 2008, a civilian nuclear agreement was signed between India and the United States. Although India possessed nuclear weapons at
13552-507: The early 16th century, northern India, then under mainly Muslim rulers, fell again to the superior mobility and firepower of a new generation of Central Asian warriors. The resulting Mughal Empire did not stamp out the local societies it came to rule. Instead, it balanced and pacified them through new administrative practices and diverse and inclusive ruling elites, leading to more systematic, centralised, and uniform rule. Eschewing tribal bonds and Islamic identity, especially under Akbar ,
13706-536: The early mediaeval era, Christianity , Islam , Judaism , and Zoroastrianism became established on India's southern and western coasts. Muslim armies from Central Asia intermittently overran India's northern plains, eventually founding the Delhi Sultanate and drawing northern India into the cosmopolitan networks of mediaeval Islam . In the 15th century, the Vijayanagara Empire created
13860-664: The east. To the south, the remaining peninsular landmass, the Deccan Plateau , is flanked on the west and east by coastal ranges known as the Western and Eastern Ghats ; the plateau contains the country's oldest rock formations, some over one billion years old. Constituted in such fashion, India lies to the north of the equator between 6° 44′ and 35° 30′ north latitude and 68° 7′ and 97° 25′ east longitude. India's coastline measures 7,517 kilometres (4,700 mi) in length; of this distance, 5,423 kilometres (3,400 mi) belong to peninsular India and 2,094 kilometres (1,300 mi) to
14014-565: The endangered Bengal tiger and the Ganges river dolphin . Critically endangered species include the gharial , a crocodilian ; the great Indian bustard ; and the Indian white-rumped vulture , which has become nearly extinct by having ingested the carrion of diclofenac -treated cattle. Before they were extensively used for agriculture and cleared for human settlement, the thorn forests of Punjab were mingled at intervals with open grasslands that were grazed by large herds of blackbuck preyed on by
14168-470: The environmental and economic impact, destruction habitat, damage historical sites, and disrupt lives in the densely-populated state. Maharashtra, Karnataka & Kerala Governments had given Green signal for doubling & electrification of Konkan Railway Line in 2015/2016. In March 1993, the southern 46-kilometre (29 mi) between Thokur , 18-kilometre (11 mi) from Mangalore , (now Mangaluru ) and Udupi in Karnataka entered service, followed by
14322-516: The first known writing medium. Clay was chosen due to the local material being easy to work with and widely available. Scribes wrote on the tablets by inscribing them with a script known as cuneiform , using a blunt reed called a stylus , which effectively produced the wedge shaped markings of their writing. After being written on, clay tablets could be reworked into fresh tablets and reused if needed, or fired to make them permanent records. Purpose-made clay balls were used as sling ammunition . Clay
14476-562: The first train to take the Roha-Veer double line on Konkan railway route on 30 August 2021. The foundation stone laying for electrification of the Konkan railway line was done in November 2015. The entire 741 kilometer route stretching from Roha, Maharashtra to Thokur, Karnataka has been electrified in March 2022. Inspection of the entire stretch was completed in six phases starting in March 2020. The last stretch between Ratnagiri and Thivim
14630-484: The lack of monsoon patrolling. The findings were disputed by the corporation, which said that the lack of monsoon patrolling did not lead to the accident (which was due to forces of nature). Shortly after the accident, however, the corporation announced that it would enhance safety measures on the route. Barely a year later, the measures were found inadequate when a second major accident occurred on 16 June 2004. A Mangalore–Mumbai Matsyaganda Express derailed and fell off
14784-494: The largest single party, was able to form a minority government led by P. V. Narasimha Rao . A two-year period of political turmoil followed the general election of 1996 . Several short-lived alliances shared power at the centre. The BJP formed a government briefly in 1996; it was followed by two comparatively long-lasting United Front coalitions, which depended on external support. There were two prime ministers during this period; H.D. Deve Gowda and I.K. Gujral . In 1998 ,
14938-478: The life of its exemplar, Mahavira . Buddhism , based on the teachings of Gautama Buddha , attracted followers from all social classes excepting the middle class; chronicling the life of the Buddha was central to the beginnings of recorded history in India. In an age of increasing urban wealth, both religions held up renunciation as an ideal, and both established long-lasting monastic traditions. Politically, by
15092-504: The line began after the inauguration of the full 756.25-kilometre (469.91 mi) stretch from Roha to Mangalore on 26 January 1998. Passenger service on the full route, between Mumbai and Mangalore, began in May 1998. According to a study by the railway, track doubling is possible on about 324-kilometre (201 mi) which runs on the plains. Several stretches on the 756.25-kilometre (469.91 mi) line can be converted to double track, such as
15246-489: The line by about 27.75 kilometres (17.24 mi) but reduce environmental damage. But the hinterland alignment was rejected by the Konkan Railway Corporation because it would substantially lengthen & divert the line, deny rail access to Goa's population centers, and delay and increase the costs of construction. The KRRAC, which had become a political movement, filed public interest litigation in
15400-526: The loose-knit Maurya and Gupta Empires based in the Ganges Basin . Their collective era was suffused with wide-ranging creativity, but also marked by the declining status of women, and the incorporation of untouchability into an organised system of belief. In South India , the Middle kingdoms exported Dravidian-languages scripts and religious cultures to the kingdoms of Southeast Asia . In
15554-471: The majority of India's rainfall. Four major climatic groupings predominate in India: tropical wet , tropical dry , subtropical humid , and montane . Temperatures in India have risen by 0.7 °C (1.3 °F) between 1901 and 2018. Climate change in India is often thought to be the cause. The retreat of Himalayan glaciers has adversely affected the flow rate of the major Himalayan rivers, including
15708-404: The material. The clay mineral kaolinite is transformed into a non-clay material, metakaolin , which remains rigid and hard if moistened again. Further firing through the stoneware and porcelain stages further recrystallizes the metakaolin into yet stronger minerals such as mullite . The tiny size and plate form of clay particles gives clay minerals a high surface area. In some clay minerals,
15862-488: The monsoon to 75 km/h (47 mph) from 120 km/h (75 mph) and engineering measures such as boulder netting, shotcreting , rock bolting , micropiling and vetiver plantations along the line to improve safety. A goods train carrying fertilizers derailed between Diwankhavti and Khed stations (83/7Km) at 15:57 on 10 May 2020. This happened during COVID-19 lockdown when regular passenger and goods trains were stopped by Central or Union government of India. There
16016-724: The moulded clay is just dry enough to hold its shape. The plastic limit of kaolinite clay ranges from about 36% to 40% and its liquid limit ranges from about 58% to 72%. High-quality clay is also tough, as measured by the amount of mechanical work required to roll a sample of clay flat. Its toughness reflects a high degree of internal cohesion. Clay has a high content of clay minerals that give it its plasticity. Clay minerals are hydrous aluminium phyllosilicate minerals , composed of aluminium and silicon ions bonded into tiny, thin plates by interconnecting oxygen and hydroxide ions. These plates are tough but flexible, and in moist clay, they adhere to each other. The resulting aggregates give clay
16170-420: The nation to liberalise its economy ; since then, it has moved increasingly towards a free-market system by emphasising both foreign trade and direct investment inflows. India has been a member of World Trade Organization since 1 January 1995. The 522-million-worker Indian labour force is the world's second largest , as of 2017 . The service sector makes up 55.6% of GDP, the industrial sector 26.3% and
16324-445: The newly canalled Punjab, led to increased food production for internal consumption. The railway network provided critical famine relief, notably reduced the cost of moving goods, and helped nascent Indian-owned industry. After World War I , in which approximately one million Indians served , a new period began. It was marked by British reforms but also repressive legislation , by more strident Indian calls for self-rule, and by
16478-405: The night of 22 June 2003, when a landslide derailed a Karwar –Mumbai express train at the entrance to a tunnel. Fifty-one people died as a result of the accident, and others were injured. As a result, the corporation was severely criticised for failing to take adequate safety measures in the landslide-prone region. An inquiry reported that the cause of the accident was the failure of a cutting due to
16632-566: The northern 47-kilometre (29 mi) section between Roha and Veer in Maharashtra in June of that year. The first passenger train on the route ran between Mangalore and Udupi on 20 March 1993. The service was extended by 52 kilometres (32 mi) from Veer to Khed in March 1995, and by a further 286 kilometres (178 mi) from Khed to Sawantwadi Road in December 1996. The Southern service
16786-682: The northwest. Its evidence today is found in the hymns of the Rigveda . Preserved by an oral tradition that was resolutely vigilant , the Rigveda records the dawning of Hinduism in India. The Dravidian languages of India were supplanted in the northern and western regions. By 400 BCE , stratification and exclusion by caste had emerged within Hinduism, and Buddhism and Jainism had arisen, proclaiming social orders unlinked to heredity. Early political consolidations gave rise to
16940-467: The plates carry a negative electrical charge that is balanced by a surrounding layer of positive ions ( cations ), such as sodium, potassium, or calcium. If the clay is mixed with a solution containing other cations, these can swap places with the cations in the layer around the clay particles, which gives clays a high capacity for ion exchange . The chemistry of clay minerals, including their capacity to retain nutrient cations such as potassium and ammonium,
17094-634: The press that track-doubling and electrification would begin on 8 November in Kolad. Life Insurance Corporation offered a favourable ₹ 2.5 billion loan, and other funding would be available. The project, expected to cost ₹ 100 billion, was scheduled for completion by 2020. In October 2018, the railway announced that the 45-kilometre (28 mi) stretch between Roha and Veer would have two tracks by December 2019. Matsyagandha Express ( Train number 02619 run as special) travelling from Lokmanya Tilak Terminus, Mumbai (LTT) to Mangaluru Central (MAQ) became
17248-446: The project were given to construction firms which included Larsen & Toubro who were given a major part of the project, Gammon India and Afcons . To speed up construction, piers for major bridges were cast on riverbanks itself and launched with pontoon -mounted cranes. This was India's first use of incremental launch bridge-building. The greatest challenge was presented by the nine tunnels bored through soft soil, which required
17402-536: The project's importance) did so voluntarily. This enabled the process to be completed in one year. The longest bridge is on the River Sharavathi, spanning 2.06 km (1.28 mi) and the longest Tunnel is in Karbude near Ratnagiri, stretching 6.561 km (4.08 mi). Terrain and the elements were challenging; flash floods, loose soil, landslides and tunnel collapses affected work at many places on
17556-482: The project. Thickly-forested construction sites were often visited by wild animals. The route crosses three states ( Maharashtra , Goa and Karnataka ), each of which agreed to provide financing. The authorised share capital was increased in 1996-1997 from ₹ 6 billion to ₹ 8 billion, with the government of India taking a 51-percent share; the rest went to Maharashtra (22 percent), Karnataka (15 percent), Kerala (6 percent) and Goa (6 percent). Contracts for
17710-546: The proportion of the area of a forest covered by its tree canopy . Very dense forest , whose canopy density is greater than 70%, occupies 3.02% of India's land area. It predominates in the tropical moist forest of the Andaman Islands , the Western Ghats , and Northeast India . Moderately dense forest , whose canopy density is between 40% and 70%, occupies 9.39% of India's land area. It predominates in
17864-508: The proposed railway line. The KRRAC's main points were that the proposal would flood coastal regions, destroy fertile land, harm the monuments of Old Goa , irreparably damage the marshes and mangrove swamps along the coast and the estuaries of the Mandovi and Zuari Rivers, and displace neighbourhoods along the coast. The committee proposed an alternative hinterland alignment passing through relatively-unpopulated regions, which would extend
18018-450: The region highly diverse, second only to Africa in human genetic diversity . Settled life emerged on the subcontinent in the western margins of the Indus river basin 9,000 years ago, evolving gradually into the Indus Valley Civilisation of the third millennium BCE. By at least 1200 BCE , an archaic form of Sanskrit , an Indo-European language , had diffused into India from
18172-497: The route and extended to Ernakulam Junction on 1 August 1998. The Pune -Ernakulam Junction Express was introduced on 25 February 1999. The Marusagar Express , which runs between Jaipur and Ernakulam Junction and was extended to Ajmer via the Konkan Railway, began service on 12 October 2001. The Jan Shatabdi Express was flagged off between Mumbai and Madgaon (the longest-running Jan Shatabdi) on 16 April 2002 to commemorate Indian Railways' 150th anniversary. On 1 February 2008,
18326-548: The seas, greater resources, and more advanced military training and technology led it to increasingly assert its military strength and caused it to become attractive to a portion of the Indian elite; these factors were crucial in allowing the company to gain control over the Bengal region by 1765 and sideline the other European companies. Its further access to the riches of Bengal and the subsequent increased strength and size of its army enabled it to annex or subdue most of India by
18480-696: The separation to occur at a particle size of 2 μm (clays being finer than silts), sedimentologists often use 4–5 μm, and colloid chemists use 1 μm. Clay-size particles and clay minerals are not the same, despite a degree of overlap in their respective definitions. Geotechnical engineers distinguish between silts and clays based on the plasticity properties of the soil, as measured by the soils' Atterberg limits . ISO 14688 grades clay particles as being smaller than 2 μm and silt particles as being larger. Mixtures of sand , silt and less than 40% clay are called loam . Some clay minerals (such as smectite ) are described as swelling clay minerals, because they have
18634-463: The share of external trade in India's GDP stood at 24%, up from 6% in 1985. In 2008, India's share of world trade was 1.7%; In 2021, India was the world's ninth-largest importer and the sixteenth-largest exporter . Major exports include petroleum products, textile goods, jewellery, software, engineering goods, chemicals, and manufactured leather goods. Major imports include crude oil, machinery, gems, fertiliser, and chemicals. Between 2001 and 2011,
18788-841: The site of formation. Secondary clays are clays that have been transported from their original location by water erosion and deposited in a new sedimentary deposit. Secondary clay deposits are typically associated with very low energy depositional environments such as large lakes and marine basins. The main groups of clays include kaolinite , montmorillonite - smectite , and illite . Chlorite , vermiculite , talc , and pyrophyllite are sometimes also classified as clay minerals. There are approximately 30 different types of "pure" clays in these categories, but most "natural" clay deposits are mixtures of these different types, along with other weathered minerals. Clay minerals in clays are most easily identified using X-ray diffraction rather than chemical or physical tests. Varve (or varved clay )
18942-637: The southern supercontinent Gondwana , began a north-eastward drift caused by seafloor spreading to its south-west, and later, south and south-east. Simultaneously, the vast Tethyan oceanic crust , to its northeast, began to subduct under the Eurasian Plate . These dual processes, driven by convection in the Earth's mantle , both created the Indian Ocean and caused the Indian continental crust eventually to under-thrust Eurasia and to uplift
19096-416: The subcontinent from the north-west. The caste system , which created a hierarchy of priests, warriors, and free peasants, but which excluded indigenous peoples by labelling their occupations impure, arose during this period. On the Deccan Plateau , archaeological evidence from this period suggests the existence of a chiefdom stage of political organisation. In South India , a progression to sedentary life
19250-526: The subcontinent transitioned from the Chalcolithic cultures to the Iron Age ones. The Vedas , the oldest scriptures associated with Hinduism , were composed during this period, and historians have analysed these to posit a Vedic culture in the Punjab region and the upper Gangetic Plain . Most historians also consider this period to have encompassed several waves of Indo-Aryan migration into
19404-441: The subcontinent, thereby creating a syncretic Indo-Islamic culture in the north. The sultanate's raiding and weakening of the regional kingdoms of South India paved the way for the indigenous Vijayanagara Empire . Embracing a strong Shaivite tradition and building upon the military technology of the sultanate, the empire came to control much of peninsular India, and was to influence South Indian society for long afterwards. In
19558-414: The support of left-leaning parties and MPs who opposed the BJP. The UPA returned to power in the 2009 general election with increased numbers, and it no longer required external support from India's communist parties . That year, Manmohan Singh became the first prime minister since Jawaharlal Nehru in 1957 and 1962 to be re-elected to a consecutive five-year term. In the 2014 general election ,
19712-677: The time and was not a party to the Nuclear Non-Proliferation Treaty, it received waivers from the International Atomic Energy Agency and the Nuclear Suppliers Group , ending earlier restrictions on India's nuclear technology and commerce. As a consequence, India became the sixth de facto nuclear weapons state. India subsequently signed co-operation agreements involving civilian nuclear energy with Russia, France,
19866-518: The two nations have gone to war four times: in 1947 , 1965 , 1971 , and 1999 . Three of these wars were fought over the disputed territory of Kashmir , while the third, the 1971 war, followed from India's support for the independence of Bangladesh . In the late 1980s, the Indian military twice intervened abroad at the invitation of the host country: a peace-keeping operation in Sri Lanka between 1987 and 1990; and an armed intervention to prevent
20020-639: The union territories of Jammu and Kashmir , Puducherry and the National Capital Territory of Delhi , have elected legislatures and governments following the Westminster system of governance. The remaining five union territories are directly ruled by the central government through appointed administrators. In 1956, under the States Reorganisation Act , states were reorganised on a linguistic basis. There are over
20174-548: The useful properties of clay. Some of the earliest pottery shards recovered are from central Honshu , Japan . They are associated with the Jōmon culture, and recovered deposits have been dated to around 14,000 BCE. Cooking pots, art objects, dishware, smoking pipes , and even musical instruments such as the ocarina can all be shaped from clay before being fired. Ancient peoples in Mesopotamia adopted clay tablets as
20328-426: The water molecules are removed, and the plates hydrogen bond directly to each other, so that the dried clay is rigid but still fragile. If the clay is moistened again, it will once more become plastic. When the clay is fired to the earthenware stage, a dehydration reaction removes additional water from the clay, causing clay plates to irreversibly adhere to each other via stronger covalent bonding , which strengthens
20482-531: The west; China , Nepal , and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives ; its Andaman and Nicobar Islands share a maritime border with Thailand , Myanmar, and Indonesia . Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago. Their long occupation, initially in varying forms of isolation as hunter-gatherers, has made
20636-495: The western part of the Indo-Gangetic plain, now turned into rich agricultural land by irrigation, its features no longer visible. Among the Indian subcontinent's notable indigenous trees are the astringent Azadirachta indica , or neem , which is widely used in rural Indian herbal medicine , and the luxuriant Ficus religiosa , or peepul , which is displayed on the ancient seals of Mohenjo-daro , and under which
20790-444: The world in nominal per capita income and 125th in per capita income adjusted for purchasing power parity (PPP)—the vast majority of Indians fall into the low-income group. Until 1991, all Indian governments followed protectionist policies that were influenced by socialist economics. Widespread state intervention and regulation largely walled the economy off from the outside world. An acute balance of payments crisis in 1991 forced
20944-437: The world's most populous democracy since the time of its independence in 1947. It is a pluralistic , multilingual and multi-ethnic society . India's nominal per capita income increased from US$ 64 annually in 1951 to US$ 2,601 in 2022, and its literacy rate from 16.6% to 74%. During the same time, its population grew from 361 million to almost 1.4 billion, and India became the most populous country in 2023. From being
21098-537: The world's newer nations; however, in spite of its recent economic successes, freedom from want for its disadvantaged population remains a goal yet to be achieved. India accounts for the bulk of the Indian subcontinent, lying atop the Indian tectonic plate , a part of the Indo-Australian Plate . India's defining geological processes began 75 million years ago when the Indian Plate, then part of
21252-735: The world's population live or work in buildings made with clay, often baked into brick, as an essential part of its load-bearing structure. Clay is a very common substance. Shale , formed largely from clay, is the most common sedimentary rock. Although many naturally occurring deposits include both silts and clay, clays are distinguished from other fine-grained soils by differences in size and mineralogy. Silts , which are fine-grained soils that do not include clay minerals, tend to have larger particle sizes than clays. Mixtures of sand , silt and less than 40% clay are called loam . Soils high in swelling clays ( expansive clay ), which are clay minerals that readily expand in volume when they absorb water, are
21406-493: The world's population, in both traditional societies as well as developed countries, still live or work in buildings made with clay, often baked into brick, as an essential part of their load-bearing structure. Also a primary ingredient in many natural building techniques, clay is used to create adobe , cob , cordwood , and structures and building elements such as wattle and daub , clay plaster, clay render case, clay floors and clay paints and ceramic building material . Clay
21560-412: Was also introduced by Indian Railways , with modern on-board facilities.
