Lakshadweep
Lakshadweep () is a union territory of India. It is an archipelago of 36 islands divided into three island subgroups: the Amindivi Islands in the north, the Laccadive Islands (separated from Amindivi roughly by the 11th parallel north), and the atoll of Minicoy to the south of the Nine Degree Channel.

Indian Standard Time
Indian Standard Time (IST), sometimes also called India Standard Time, is the time zone observed throughout the Republic of India, with a time offset of UTC+05:30. India does not observe daylight saving time or other seasonal adjustments. In military and aviation time, IST is designated E* ("Echo-Star"). It is indicated as ''Asia/Kolkata'' in the IANA time zone database. History The Indian Standard Time was adopted on 1 January 1906 during the British era with the phasing out of its precursor Madras Time (Railway Time), and after Independence in 1947, the Union government established IST as the official time for the whole country, although Kolkata and Mumbai retained their own local time (known as Calcutta Time and Bombay Time) until 1948 and 1955, respectively. The Central observatory was moved from Chennai to a location at Shankargarh Fort in Allahabad district, so that it would be as close to UTC+05:30 as possible. Daylight Saving Time (DST) was used brief ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reefs Of India
A reef is a ridge or shoal of rock, coral, or similar relatively stable material lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic (non-living) processes such as deposition of sand or wave erosion planning down rock outcrops. However, reefs such as the coral reefs of tropical waters are formed by biotic (living) processes, dominated by corals and coralline algae. Artificial reefs, such as shipwrecks and other man-made underwater structures, may occur intentionally or as the result of an accident. These are sometimes designed to increase the physical complexity of featureless sand bottoms to attract a more diverse range of organisms. They provide shelter to various aquatic animals which help prevent extinction. Another reason reefs are put in place is for aquaculture, and fish farmers who are looking to improve their businesses sometimes invest in them. Reefs are often quite near to the surface, but not all definitions require this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Undersea Banks Of Lakshadweep
An underwater environment is a environment of, and immersed in, liquid water in a natural or artificial feature (called a Water, body of water), such as an ocean, sea, lake, pond, reservoir, river, canal, or aquifer. Some characteristics of the underwater environment are universal, but many depend on the local situation. Liquid water has been present on Earth for most of the History of Earth, history of the planet. The underwater environment is thought to be the place of the origin of life on Earth, and it remains the ecological region most critical to the support of life and the natural habitat of the majority of living organisms. Several branches of science are dedicated to the study of this environment or specific parts or aspects of it. A number of human activities are conducted in the more accessible parts of the underwater environment. These include research, underwater diving for work or recreation, and underwater warfare with submarines. It is hostile to humans in many ...

Cherbaniani Reef
Cherbaniani Reef, also known as Beleapani Reef (), is a coral atoll belonging to the Amindivi Subgroup of islands of the Union Territory of Lakshadweep, India. It has a distance of south of the city of Delhi. Geography Cherbaniani Reef is located 33 km north of Byramgore Reef and at it is the northwesternmost feature of Lakshadweep. The atoll has a roughly oval shape and was first described by ornithologist Allan Hume in 1876; its total lagoon area is . The 14 km long coral reef that encloses the lagoon has three small uninhabited islands on it. Ecology They are composed of accumulated coral sand, shingle, cuttle-bones and sea shells. There are many land hermit crabs under the boulders and among the detritus. The atoll used to be a breeding ground for pelagic birds, including the sooty tern (''Sterna fuliginosa'') and brown noddy (''Anous stolidus''), which were formerly found in great numbers.

Lagoon
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into ''coastal lagoons'' (or ''barrier lagoons'') and ''atoll lagoons''. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as Estuary, estuaries. Lagoons are common coastal features around many parts of the world. Definition and terminology Lagoons are shallow, often elongated bodies of water separated from a larger body of water by a shallow or exposed shoal, reef, coral reef, or similar feature. Some authorities include fresh water bodies in the definition of "lagoon", while others explicitly restrict "lagoon" to bodies of water with some degree of salinity. The distinction between "lagoon" and "estuary" also varies between authorities. Richard A. Davis J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delhi
Delhi, officially the National Capital Territory (NCT) of Delhi, is a city and a union territory of India containing New Delhi, the capital of India. Straddling the Yamuna river, but spread chiefly to the west, or beyond its Bank (geography), right bank, Delhi shares borders with the state of Uttar Pradesh in the east and with the state of Haryana in the remaining directions. Delhi became a union territory on 1 November 1956 and the NCT in 1995. The NCT covers an area of . According to the 2011 census, Delhi's city proper population was over 11 million, while the NCT's population was about 16.8 million. The topography of the medieval fort Purana Qila on the banks of the river Yamuna matches the literary description of the citadel Indraprastha in the Sanskrit epic ''Mahabharata''; however, excavations in the area have revealed no signs of an ancient built environment. From the early 13th century until the mid-19th century, Delhi was the capital of two major empires, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Union Territory
Among the states and union territories of India, a Union Territory (UT) is a region that is directly governed by the Government of India, central government of India, as opposed to the states, which have their own State governments of India, state government systems. Unlike states, Union Territories do not have their own full-fledged government but are administered by a Lieutenant governor or Administrator appointed by the President of India. Union Territories are created for various reasons, including geographical importance, strategic necessity, or historical factors. These areas are under the control of the central government to ensure uniformity in governance across the country. Some Union Territories, such as Delhi (National Capital Territory) and Puducherry (union territory), Puducherry, have been granted special status and are allowed to have their own legislative assemblies, which can pass laws on certain matters, though the central government still retains significant ...

Amindivi
The Aminidivi Islands () are one of the three island subgroups in the Union Territory of Lakshadweep, India. It is the northern group of the Lakshadweep, separated from the Laccadive Islands subgroup roughly by the 11th parallel north. The total land area of the group is 9.26 km2. Formerly the Union Territory was known as Laccadive, Minicoy, and Amindivi Islands, a name that was changed to Lakshadweep by an act of Parliament in 1973. The Aminidivi group forms a taluka or subdivision. The islands of Amini, Kiltan, Chetlat, Kadmat and Bitra are inhabited. The population numbered 18,876 at the 2001 census and Islam is the main religion of the islanders. Aminidivi has the highest recorded rainfall in India in a 24-hour period, at 1,168 mm on 2004-05-06. Geography Aminidivi consists of atolls with islands, three reefs or atolls with only unvegetated sand cays above the high water mark, and four submerged banks.

Atoll
An atoll () is a ring-shaped island, including a coral rim that encircles a lagoon. There may be coral islands or cays on the rim. Atolls are located in warm tropical or subtropical parts of the oceans and seas where corals can develop. Most of the approximately 440 atolls in the world are in the Pacific Ocean. Two different, well-cited models, the subsidence model and the antecedent karst model, have been used to explain the development of atolls.Droxler, A.W. and Jorry, S.J., 2021. "The Origin of Modern Atolls: Challenging Darwin's Deeply Ingrained Theory". ''Annual Review of Marine Science'', 13, pp. 537–573. According to Charles Darwin's subsidence model, the formation of an atoll is explained by the sinking of a volcanic island around which a coral fringing reef has formed. Over geologic time, the volcanic island becomes extinct and eroded as it subsides completely beneath the surface of the ocean. As the volcanic island subsides, the coral fringing reef becomes a ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
