Lakshadweep
Lakshadweep (), also known as Laccadives (), is a union territory of India. It is an archipelago of 36 islands in the Arabian sea, located off the Malabar Coast. The name ''Lakshadweep'' means "one lakh islands" in Sanskrit, though the Laccadive Islands are just one part of the archipelago of no more than a hundred islands. Malayalam is the primary as well as the widely spoken native language in the territory. The islands form the smallest union territory of India and their total surface area is just . The lagoon area covers about , the territorial waters area and the exclusive economic zone area . 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, Chagos-Lakshadweep Ridge ...

Indian Standard Time
Indian Standard Time (IST), sometimes also called India Standard Time, is the time zone observed throughout 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 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 briefly during the China–India War of 1962 and the Indo-Pakistani Wars of 1965 and 1971. Calculation Indian Standard Time is calculated from the clock tower in Mirzapur nearly exa ... [...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 processes— deposition of sand, wave erosion planing down rock outcrops, etc.—but there are also reefs such as the coral reefs of tropical waters formed by biotic processes dominated by corals and coralline algae, and artificial reefs such as shipwrecks and other anthropogenic underwater structures may occur intentionally or as the result of an accident, and sometimes have a designed role in enhancing the physical complexity of featureless sand bottoms, to attract a more diverse assemblage of organisms. Reefs are often quite near to the surface, but not all definitions require this. Earth's largest coral reef system is the Great Barrier Reef in Australia, at a length of over . Biotic There is a variety of biotic reef types, including oyster reefs and sponge reefs, but the most massive and widely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Undersea Banks Of Lakshadweep
The underwater environment is the region below the surface of, and immersed in, liquid water in a natural or artificial feature (called a 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 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 ways an ...

Sesostris Bank
Sesostris Bank is a submerged bank or sunken atoll belonging to the Amindivi Subgroup of islands of the Union Territory of Lakshadweep, India, and has a distance of south of the city of Delhi. Geography It is the second largest feature of Lakshadweep, after Bassas de Pedro, with a lagoon area of . It is also one of the northernmost features, after Cora Divh and Bassas de Pedro. Those coral banks, all submerged, form the north of Lakshadweep. Sesostris Bank is about 22 km in diameter. There are no emergent cays or islands. Depths range from 20 to 77 meters. Depths near the bank reach 700 meters. This bank was named after the steam frigate of the Indian Navy.''China Trade and Empire: Jardine, Matheson & Co. and the Origins of British Rule in Hong Kong, 1827-1843'', Alain Le Pichon (Editor), Oxford University Press, 2006, Administration The bank belongs to the township of Chetlat Island of Aminidivi Tehsil A tehsil (, also known as tahsil, taluka, or taluk) is a local ...

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 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, 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 Jr. restrict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 partially or completely. There may be coral islands or cays on the rim. Atolls are located in warm tropical or subtropical oceans and seas where corals can grow. Most of the approximately 440 atolls in the world are in the Pacific Ocean. Two different, well-cited models, the subsidence and antecedent karst models, 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 subsidence 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 ...
