Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Body of water
–
A body of water or waterbody is any significant accumulation of water, generally on a planets surface. The term most often refers to oceans, seas, and lakes, a body of water does not have to be still or contained, Rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water. Most are naturally occurring geographical features, but some are artificial, there are types that can be either. For example, most reservoirs are created by engineering dams, similarly, most harbors are naturally occurring bays, but some harbors have been created through construction. Bodies of water that are navigable are known as waterways, some bodies of water collect and move water, such as rivers and streams, and others primarily hold water, such as lakes and oceans. The term body of water can also refer to a reservoir of water held by a plant, note that there are some geographical features involving water that are not bodies of water, for example waterfalls, geysers and rapids. Arm of the sea - also sea arm, used to describe a sea loch, arroyo - a usually dry creek bed or gulch that temporarily fills with water after a heavy rain, or seasonally. Artificial lake or artificial pond - see reservoir or impoundment, barachois - a lagoon separated from the ocean by a sand bar. Bay - an area of water bordered by land on three sides, similar to, but smaller than a gulf, bayou - a slow-moving stream or a marshy lake. Bight - a large and often only slightly receding bay, or a bend in any geographical feature, billabong - see Oxbow lake, a pond or still body of water created when a river changes course and some water becomes trapped. Boil - see Seep Brook - a small stream, canal - an artificial waterway, usually connected to existing lakes, rivers, or oceans. Channel - the physical confine of a river, slough or ocean consisting of a bed. See also stream bed and strait, earth scientists generally use the term to describe a circular or round inlet with a narrow entrance, though colloquially the term is sometimes used to describe any sheltered bay. Basin - a region of land where water from rain or snowmelt drains downhill into another body of water, such as a river, lake, creek - an inlet of the sea, narrower than a cove. Delta - the location where a river flows into an ocean, sea, estuary, lake, distributary or distributary channel - a stream that branches off and flows away from a main stream channel. Draw - a usually dry creek bed or gulch that temporarily fills with water after a heavy rain, fjord - a submergent landform which has occurred due to glacial activity. Glacier - a large collection of ice or a river that moves slowly down a mountain. Glacial Pothole - see Kettle Gulf - a part of a lake or ocean that extends so that it is surrounded by land on three sides, similar to, but larger than a bay, headland - an area of water bordered by land on three sides

Sea
–
A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, the sea is the system of Earths salty. The sea moderates Earths climate and has important roles in the cycle, carbon cycle. Although the sea has been traveled and explored since prehistory, the scientific study of the sea—oceanography—dates broadly to the British Challenger expedition of the 1870s. Owing to the present state of continental drift, the Northern Hemisphere is now equally divided between land and sea but the South is overwhelmingly oceanic. Salinity in the ocean is generally in a narrow band around 3. 5% by mass, although this can vary in more landlocked waters, near the mouths of large rivers. About 85% of the solids in the sea are sodium chloride. Deep-sea currents are produced by differences in salinity and temperature, surface currents are formed by the friction of waves produced by the wind and by tides, the changes in local sea level produced by the gravity of the Moon and Sun. The direction of all of these is governed by surface and submarine land masses, former changes in sea levels have left continental shelves, shallow areas in the sea close to land. The most diverse areas surround great tropical coral reefs, whaling in the deep sea was once common but whales dwindling numbers prompted international conservation efforts and finally a moratorium on most commercial hunting. Life may have started there and aquatic microbial mats are generally credited with the oxygenation of Earths atmosphere, the sea is an essential aspect of human trade, travel, mineral extraction, and power generation. It is the scene of activities including swimming, diving, surfing. However, population growth, industrialization, and intensive farming have all contributed to marine pollution. Atmospheric carbon dioxide is being absorbed in increasing amounts, lowering its pH in a known as ocean acidification. The shared nature of the sea has made overfishing an increasing problem, both senses of sea date to Old English, the larger sense has required a definite article since Early Middle English. Seas are generally larger than lakes and contain salt water, while the defining elements of size and being bounded are generally used, there is no formally accepted technical definition of sea among oceanographers. In international law, the United Nations Convention on the Law of the Sea states that all the ocean is the sea. Earth is the known planet with seas of liquid water on its surface, although Mars possesses ice caps

Drainage basin
–
A drainage basin or catchment area is any area of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water. Drainage basins connect into other drainage basins at elevations in a hierarchical pattern, with smaller sub-drainage basins. Other terms used to describe drainage basins are catchment, catchment basin, drainage area, river basin and water basin. In closed drainage basins the water converges to a point inside the basin, known as a sink, which may be a permanent lake. The drainage basin acts as a funnel by collecting all the water within the covered by the basin. Each drainage basin is separated topographically from adjacent basins by a perimeter, drainage basins are similar but not identical to hydrologic units, which are drainage areas delineated so as to nest into a multi-level hierarchical drainage system. Hydrologic units are defined to allow multiple inlets, outlets, or sinks, in a strict sense, all drainage basins are hydrologic units but not all hydrologic units are drainage basins. Drainage basins of the oceans and seas of the world. Grey areas are endorheic basins that do not drain to the oceans, the following is a list of the major ocean basins, About 48. 7% of the worlds land drains to the Atlantic Ocean. The two major mediterranean seas of the world also flow to the Atlantic, The Caribbean Sea and Gulf of Mexico basin includes most of the U. S. The Mediterranean Sea basin includes much of North Africa, east-central Africa, Southern, Central, and Eastern Europe, Turkey, and the areas of Israel, Lebanon. Just over 13% of the land in the world drains to the Pacific Ocean, the Indian Oceans drainage basin also comprises about 13% of Earths land. It drains the eastern coast of Africa, the coasts of the Red Sea and the Persian Gulf, the Indian subcontinent, Burma, antarctica comprises approximately eight percent of the Earths land. The five largest river basins, from largest to smallest, are the basins of the Amazon, the Río de la Plata, the Congo, the Nile, and the Mississippi. The three rivers that drain the most water, from most to least, are the Amazon, Ganga, endorheic drainage basins are inland basins that do not drain to an ocean. Around 18% of all land drains to endorheic lakes or seas or sinks, the largest of these consists of much of the interior of Asia, which drains into the Caspian Sea, the Aral Sea, and numerous smaller lakes. Some of these, such as the Great Basin, are not single drainage basins but collections of separate, in endorheic bodies of standing water where evaporation is the primary means of water loss, the water is typically more saline than the oceans. An extreme example of this is the Dead Sea, drainage basins have been historically important for determining territorial boundaries, particularly in regions where trade by water has been important

India
–
India, officially the Republic of India, is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and it is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west, China, Nepal, and Bhutan to the northeast, in the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. Indias Andaman and Nicobar Islands share a border with Thailand. The Indian subcontinent was home to the urban Indus Valley Civilisation of the 3rd millennium BCE, in the following millennium, the oldest scriptures associated with Hinduism began to be composed. Social stratification, based on caste, emerged in the first millennium BCE, early political consolidations took place under the Maurya and Gupta empires, the later peninsular Middle Kingdoms influenced cultures as far as southeast Asia. In the medieval era, Judaism, Zoroastrianism, Christianity, and Islam arrived, much of the north fell to the Delhi sultanate, the south was united under the Vijayanagara Empire. The economy expanded in the 17th century in the Mughal empire, in the mid-18th century, the subcontinent came under British East India Company rule, and in the mid-19th under British crown rule. A nationalist movement emerged in the late 19th century, which later, under Mahatma Gandhi, was noted for nonviolent resistance, in 2015, the Indian economy was the worlds seventh largest by nominal GDP and third largest by purchasing power parity. Following market-based economic reforms in 1991, India became one of the major economies and is considered a newly industrialised country. However, it continues to face the challenges of poverty, corruption, malnutrition, a nuclear weapons state and regional power, it has the third largest standing army in the world and ranks sixth in military expenditure among nations. India is a constitutional republic governed under a parliamentary system. It is a pluralistic, multilingual and multi-ethnic society and is home to a diversity of wildlife in a variety of protected habitats. The name India is derived from Indus, which originates from the Old Persian word Hindu, the latter term stems from the Sanskrit word Sindhu, which was the historical local appellation for the Indus River. The ancient Greeks referred to the Indians as Indoi, which translates as The people of the Indus, the geographical term Bharat, which is recognised by the Constitution of India as an official name for the country, is used by many Indian languages in its variations. Scholars believe it to be named after the Vedic tribe of Bharatas in the second millennium B. C. E and it is also traditionally associated with the rule of the legendary emperor Bharata. Gaṇarājya is the Sanskrit/Hindi term for republic dating back to the ancient times, hindustan is a Persian name for India dating back to the 3rd century B. C. E. It was introduced into India by the Mughals and widely used since then and its meaning varied, referring to a region that encompassed northern India and Pakistan or India in its entirety

Sri Lanka
–
Sri Lanka, officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia near south-east India. Sri Lanka has maritime borders with India to the northwest and the Maldives to the southwest, Sri Lankas documented history spans 3,000 years, with evidence of pre-historic human settlements dating back to at least 125,000 years. Its geographic location and deep harbours made it of strategic importance from the time of the ancient Silk Road through to World War II. Sri Lanka was known from the beginning of British colonial rule until 1972 as Ceylon, Sri Lankas recent history has been marred by a thirty-year civil war which decisively ended when the Sri Lankan military defeated the Liberation Tigers of Tamil Eelam in 2009. A diverse and multicultural country, Sri Lanka is home to many religions, ethnic groups, in addition to the majority Sinhalese, it is home to large groups of Sri Lankan and Indian Tamils, Moors, Burghers, Malays, Kaffirs and the aboriginal Vedda. Sri Lanka has a rich Buddhist heritage, and the first known Buddhist writings of Sri Lanka, Sri Lanka is a republic and a unitary state governed by a semi-presidential system. The legislative capital, Sri Jayawardenepura Kotte, is a suburb of the capital and largest city. Along with the Maldives, Sri Lanka is one of the two countries in South Asia that are rated among high human development on the Human Development Index. In antiquity, Sri Lanka was known to travellers by a variety of names, according to the Mahavamsa, the legendary Prince Vijaya named the land Tambapanni, because his followers hands were reddened by the red soil of the area. In Hindu mythology, such as the Mahabharata, the island was referred to as Lankā, in Tamil, the island is referred to as Eelam. Ancient Greek geographers called it Taprobanā or Taprobanē from the word Tambapanni, as a British crown colony, the island was known as Ceylon, it achieved independence as the Dominion of Ceylon in 1948. The country is known in Sinhalese as Śrī Laṃkā and in Tamil as Ilaṅkai, in 1972, its formal name was changed to Free, Sovereign and Independent Republic of Sri Lanka. Later in 1978 it was changed to the Democratic Socialist Republic of Sri Lanka, as the name Ceylon still appears in the names of a number of organisations, the Sri Lankan government announced in 2011 a plan to rename all those over which it has authority. The pre-history of Sri Lanka goes back 125,000 years, the era spans the Palaeolithic, Mesolithic and early Iron Ages. Among the Paleolithic human settlements discovered in Sri Lanka, Pahiyangala and it is said that Kubera was overthrown by his demon stepbrother Ravana, the powerful emperor who built a mythical flying machine named Dandu Monara. The modern city of Wariyapola is described as Ravanas airport, early inhabitants of Sri Lanka were probably ancestors of the Vedda people, an indigenous people numbering approximately 2,500 living in modern-day Sri Lanka. According to the Mahāvamsa, a written in Pāḷi, the original inhabitants of Sri Lanka are the Yakshas and Nagas. Ancient cemeteries that were used before 600BC and other signs of advanced civilization has also discovered in Sri Lanka

Maldives
–
The Maldives, officially the Republic of Maldives, is a South Asian island country, located in the Indian Ocean, situated in the Arabian Sea. It lies southwest of India and Sri Lanka, the chain of twenty-six atolls stretches from Ihavandhippolhu Atoll in the north to the Addu City in the south. Malé is the capital and most populated city, traditionally called the Kings Island for its central location. With an average elevation of 1.5 metres above sea level, it is the worlds lowest country, with even its highest natural point being the lowest in the world. Due to the subsequent risks posed by rising sea-levels, the government pledged in 2009 to make the Maldives a carbon-neutral country by 2019, the Maldives have been historically and culturally linked to the Indian subcontinent since the fourth century BCE. The Maldivian archipelago was Islamised in the 12th century and consolidated as a sultanate, developing commercial and cultural ties with Asia. From the mid 16th-century, the region came under the influence of European colonial powers. Independence from the United Kingdom was achieved in 1965 and a republic was established in 1968 with an elected Peoples Majlis. The ensuing decades have been characterised by political instability, efforts at democratic reform, the Maldives is a founding member of the South Asian Association for Regional Cooperation. It is also a member of the United Nations, the Organization of Islamic Cooperation, the World Bank classifies the Maldives as having an upper middle income economy. Fishing has historically been the dominant economic activity, and remains the largest sector by far, along with Sri Lanka, it is one of only two South Asian countries rated high on the Human Development Index, with its per capita income the highest among SAARC nations. The name Maldives may derive from the Malayalam words maala and dweepu or the Tamil maalai and theevu, the Maldivian people are called Dhivehin. The word theevu means island, and Dhives means islanders, the ancient Sri Lankan chronicle Mahawamsa refers to an island called Mahiladiva in Pali, which is probably a mistranslation of the same Sanskrit word meaning garland. Jan S Hogendorn, Grossman Professor of Economics, theorises that the name Maldives derives from the Sanskrit mālādvīpa, in Tamil, Garland of Islands can be translated as Malai Theevu. In Malayalam, Garland of Islands can be translated as Maladweepu, in Kannada, Garland of Islands can be translated as Maaledweepa. This is the name inscribed on the scroll in the Maldive state emblem. The classical Persian/Arabic name for Maldives is Dibajat, the Dutch referred to the islands as the Maldivische Eilanden, while the British anglicised the local name for the islands first to the Maldive Islands and later to Maldives. One such community are the Giraavaru people and they are mentioned in ancient legends and local folklore about the establishment of the capital and kingly rule in Malé

Lakshadweep
–
Lakshadweep, formerly known as the Laccadive, Minicoy, and Aminidivi Islands, is a group of islands in the Laccadive Sea,200 to 440 km off the south western coast of India. The archipelago is a Union Territory and is governed by the Union Government of India and they were also known as Laccadive Islands, although geographically this is only the name of the central subgroup of the group. Lakshadweep comes from Lakshadweepa, which one hundred thousand islands in Sanskrit. The islands form the smallest Union Territory of India, their surface area is just 32 km2. The lagoon area covers about 4,200 km2, the territorial waters area 20,000 km2, the region forms a single Indian district with 10 subdivisions. Kavaratti serves as the capital of the Union Territory and the region comes under the jurisdiction of Kerala High Court, the islands are the northernmost of the Lakshadweep-Maldives-Chagos group of islands, which are the tops of a vast undersea mountain range, the Chagos-Laccadive Ridge. As the islands do not have any aboriginal groups, different views have been postulated by the scholars about the history of habitation on these islands, archaeological evidence supports the existence of human settlement in the region around 1500 BC. The islands have long known to sailors, as indicated by an anonymous reference from the first century AD to the region in Periplus of the Erythraean Sea. The islands were referenced also in the Buddhist Jataka stories of the sixth century BC, the arrival of Muslim missionaries around the seventh century led to the advent of Islam in the region. During the medieval period, the region was ruled by the Chola dynasty, the Portuguese arrived around 1498 and were upstaged by 1545. The region was ruled by the Muslim house of Arakkal. On his death in 1799, most of the region passed on to the British and with their departure, Ten of the islands are inhabited. At the 2011 Indian census, the population of the Union Territory was 64,473, the majority of the indigenous population is Muslim and most of them belong to the Shafi school of the Sunni sect. The islanders are ethnically similar to the Malayali people of the nearest Indian state of Kerala, most of the population speaks Malayalam with Mahi being the most spoken language in Minicoy island. The islands are served by an airport on the Agatti island, the main occupation of the people is fishing and coconut cultivation, with tuna being the main item of export. A mention of the region in the Periplus of the Erythraean Sea, There are references to the control of the islands by the Cheras in the Sangam Patiṟṟuppattu. Local traditions and legends attribute the first settlement on these islands to the period of Cheraman Perumal, the oldest inhabited islands in the group are Amini, Kalpeni Andrott, Kavaratti, and Agatti. Archaeological evidence suggests that Buddhism prevailed in the region during the fifth and sixth centuries CE, according to popular tradition, Islam was brought to Lakshadweep by an Arab named Ubaidulla in 661 CE

Karnataka
–
Karnataka is a state in south western region of India. It was formed on 1 November 1956, with the passage of the States Reorganisation Act, originally known as the State of Mysore, it was renamed Karnataka in 1973. The capital and largest city is Bangalore, the state covers an area of 191,976 square kilometres, or 5.83 percent of the total geographical area of India. It is the seventh largest Indian state by area, with 61,130,704 inhabitants at the 2011 census, Karnataka is the eighth largest state by population, comprising 30 districts. Kannada, one of the languages of India, is the most widely spoken. Most of these rivers flow out of Karnataka eastward into the Bay of Bengal, though several etymologies have been suggested for the name Karnataka, the generally accepted one is that Karnataka is derived from the Kannada words karu and nādu, meaning elevated land. Karu nadu may also be read as karu, meaning black, the British used the word Carnatic, sometimes Karnatak, to describe both sides of peninsular India, south of the Krishna. With an antiquity that dates to the paleolithic, Karnataka has been home to some of the most powerful empires of ancient, the philosophers and musical bards patronised by these empires launched socio-religious and literary movements which have endured to the present day. Karnataka has contributed significantly to both forms of Indian classical music, the Carnatic and Hindustani traditions, Karnatakas pre-history goes back to a paleolithic hand-axe culture evidenced by discoveries of, among other things, hand axes and cleavers in the region. Evidence of neolithic and megalithic cultures have also found in the state. Gold discovered in Harappa was found to be imported from mines in Karnataka, prior to the third century BCE, most of Karnataka formed part of the Nanda Empire before coming under the Mauryan empire of Emperor Ashoka. Four centuries of Satavahana rule followed, allowing them to large areas of Karnataka. The decline of Satavahana power led to the rise of the earliest native kingdoms, the Kadambas, the Kadamba Dynasty, founded by Mayurasharma, had its capital at Banavasi, the Western Ganga Dynasty was formed with Talakad as its capital. These were also the first kingdoms to use Kannada in administration, as evidenced by the Halmidi inscription, the Western Chalukyas patronised a unique style of architecture and Kannada literature which became a precursor to the Hoysala art of 12th century. Parts of modern-day Southern Karnataka were occupied by the Chola Empire at the turn of 11th century, the Cholas and the Hoysalas fought over the region in the early 12th century before it eventually came under Hoysala rule. At the turn of the first millennium, the Hoysalas gained power in the region, literature flourished during this time, which led to the emergence of distinctive Kannada literary metres, and the construction of temples and sculptures adhering to the Vesara style of architecture. The expansion of the Hoysala Empire brought minor parts of modern Andhra Pradesh, in the early 14th century, Harihara and Bukka Raya established the Vijayanagara empire with its capital, Hosapattana, on the banks of the Tungabhadra River in the modern Bellary district. The empire rose as a bulwark against Muslim advances into South India, in 1565, Karnataka and the rest of South India experienced a major geopolitical shift when the Vijayanagara empire fell to a confederation of Islamic sultanates in the Battle of Talikota

Kerala
–
Kerala historically known as Keralam, is an Indian state in South India on the Malabar Coast. It was formed on 1 November 1956 following the States Reorganisation Act by combining Malayalam-speaking regions, spread over 38,863 km2, it is bordered by Karnataka to the north and northeast, Tamil Nadu to the east and south, and the Lakshadweep Sea to the west. With 33,387,677 inhabitants as per the 2011 Census, Malayalam is the most widely spoken language and is also the official language of the state. The region has been a prominent spice exporter since 3000 BCE, the Chera Dynasty was the first prominent kingdom based in Kerala, though it frequently struggled against attacks by the neighbouring Cholas and Pandyas. In the 15th century, the spice trade attracted Portuguese traders to Kerala, after independence, Travancore and Cochin joined the Republic of India and Travancore-Cochin was given the status of a state in 1949. In 1956, Kerala state was formed by merging Malabar district, Travancore-Cochin, Hinduism is practised by more than half of the population, followed by Islam and Christianity. The culture is a synthesis of Aryan and Dravidian cultures, developed over millennia, under influences from other parts of India, the production of pepper and natural rubber contributes significantly to the total national output. In the agricultural sector, coconut, tea, coffee, cashew, the states coastline extends for 595 kilometres, and around 1.1 million people in the state are dependent on the fishery industry which contributes 3% to the states income. The state has the highest media exposure in India with newspapers publishing in nine languages, mainly English, Kerala is one of the prominent tourist destinations of India, with backwaters, beaches, Ayurvedic tourism and tropical greenery as its major attractions. The name Kerala has an uncertain etymology, One popular theory derives Kerala from Kera and alam is land, thus land of coconuts, this also happens to be a nickname for the state due to abundance of coconut trees and its use by the locals. The word Kerala is first recorded in a 3rd-century BCE rock inscription left by the Maurya emperor Ashoka, the inscription refers to the local ruler as Keralaputra, or son of Chera. This contradicts the theory that Kera is from coconut tree, at that time, one of three states in the region was called Cheralam in Classical Tamil, Chera and Kera are variants of the same word. The word Cheral refers to the oldest known dynasty of Kerala kings and is derived from the Proto-Tamil-Malayalam word for lake, the earliest Sanskrit text to mention Kerala is the Aitareya Aranyaka of the Rigveda. It is also mentioned in the Ramayana and the Mahabharata, the two Hindu epics, the Skanda Purana mentions the ecclesiastical office of the Thachudaya Kaimal who is referred to as Manikkam Keralar, synonymous with the deity of the Koodalmanikyam temple. Keralam may stem from the Classical Tamil cherive-alam or chera alam, the Greco-Roman trade map Periplus Maris Erythraei refers to Keralaputra as Celobotra. According to Hindu mythology, the lands of Kerala were recovered from the sea by the warrior sage Parasurama. Parasurama threw his axe across the sea, and the water receded as far as it reached, according to legend, this new area of land extended from Gokarna to Kanyakumari. The land which rose from sea was filled with salt and unsuitable for habitation, so Parasurama invoked the Snake King Vasuki, out of respect, Vasuki and all snakes were appointed as protectors and guardians of the land
