Palk Straight
The Palk Strait ( ta, பாக்கு நீரிணை ''Pākku Nīriṇai'', si, පෝක් සමුද්ර සන්ධිය ''Pok Samudra Sandhiya'') is a strait between the Tamil Nadu state of India and the Jaffna District of the Northern Province of the island nation of Sri Lanka. It connects the Bay of Bengal in the northeast with Palk Bay in the southwest. With a minimum depth of less than 9.1 m,Palk Bay Sea Seek. it is 40 to 85 miles (64 to 137 km) wide and 85 miles long.Palk Strait Encyclopedia britannica. Several rivers flow into it, including the |

Palk Bay
Palk Bay is a semi-enclosed shallow water body between the southeast coast of India and Sri Lanka, with a water depth maximum of 13 m. Palk Bay is located between 8° 50′ and 10° North latitudes and 78° 50′ and 80° 30′ East longitudes. The width of Palk Bay ranges from 57 to 107 km and the length is around 150 km. Palk Bay is considered to be one amongst the major sinks for sediments along with Gulf of Mannar. Sediments discharged by rivers and transported by the surf currents as littoral drift settle in this sink. Few scientists have tried to understand the wave characteristics within the Palk Bay. In the southern regions close to Dhanushkodi, wind seas dominate. The north-eastern region of Palk Bay is exposed to the Bay of Bengal through the shallow Palk Strait and hence the swells can enter the Palk Bay through this opening. To the south of Palk Bay, Adam's Bridge separates Palk Bay from the Gulf of Mannar. Despite being a very shallow channel, Wave effe ...

Rama
Rama (; ), Ram, Raman or Ramar, also known as Ramachandra (; , ), is a major deity in Hinduism. He is the seventh and one of the most popular '' avatars'' of Vishnu. In Rama-centric traditions of Hinduism, he is considered the Supreme Being. Rama is said to have been born to Kaushalya and Dasharatha in Ayodhya, the ruler of the Kingdom of Kosala. His siblings included Lakshmana, Bharata, and Shatrughna. He married Sita. Though born in a royal family, their life is described in the Hindu texts as one challenged by unexpected changes such as an exile into impoverished and difficult circumstances, ethical questions and moral dilemmas. Of all their travails, the most notable is the kidnapping of Sita by demon-king Ravana, followed by the determined and epic efforts of Rama and Lakshmana to gain her freedom and destroy the evil Ravana against great odds. The entire life story of Rama, Sita and their companions allegorically discusses duties, rights and social responsibil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hindu Mythology
Hindu mythology is the body of myths and literature attributed to, and espoused by, the adherents of the Hindu religion, found in Hindu texts such as the Vedic literature, epics like ''Mahabharata'' and ''Ramayana'', the Puranas, and regional literature like the Tamil ''Periya Puranam'' and ''Divya Prabandham'', and the '' Mangal Kavya'' of Bengal. Hindu myths are also found in widely translated popular texts such as the fables of the '' Panchatantra'' and the ''Hitopadesha'', as well as in Southeast Asian texts.

Shoals
In oceanography, geomorphology, and geoscience, a shoal is a natural submerged ridge, bank, or bar that consists of, or is covered by, sand or other unconsolidated material and rises from the bed of a body of water to near the surface. It often refers to those submerged ridges, banks, or bars that rise near enough to the surface of a body of water as to constitute a danger to navigation. Shoals are also known as sandbanks, sandbars, or gravelbars. Two or more shoals that are either separated by shared troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as a shoal complex.Neuendorf, K.K.E., J.P. Mehl Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The term ''shoal'' is also used in a number of ways that can be either similar or quite different from how it is used in geologic, geomorphic, and oceanographic literature. Sometimes, this term refers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reef
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 .

Archipelago
An archipelago ( ), sometimes called an island group or island chain, is a chain, cluster, or collection of islands, or sometimes a sea containing a small number of scattered islands. Examples of archipelagos include: the Indonesian Archipelago, the Andaman and Nicobar Islands, the Lakshadweep Islands, the Galápagos Islands, the Japanese archipelago, the Philippine Archipelago, the Maldives, the Balearic Islands, The Bahamas, the Aegean Islands, the Hawaiian Islands, the Canary Islands, Malta, the Azores, the Canadian Arctic Archipelago, the British Isles, the islands of the Archipelago Sea, and Shetland. They are sometimes defined by political boundaries. For example, the Gulf archipelago off the northeastern Pacific coast forms part of a larger archipelago that geographically includes Washington state's San Juan Islands; while the Gulf archipelago and San Juan Islands are geographically related, they are not technically included in the same archipelago due to manmad ...

Significant Wave Height
In physical oceanography, the significant wave height (SWH, HTSGW or ''H''s) is defined traditionally as the mean ''wave height'' (trough to crest) of the highest third of the waves (''H''1/3). Nowadays it is usually defined as four times the standard deviation of the surface elevation – or equivalently as four times the square root of the zeroth-order moment (area) of the ''wave spectrum''. The symbol ''H''m0 is usually used for that latter definition. The significant wave height (Hs) may thus refer to ''H''m0 or ''H''1/3; the difference in magnitude between the two definitions is only a few percent. SWH is used to characterize ''sea state'', including winds and swell. Origin and definition The original definition resulted from work by the oceanographer Walter Munk during World War II. The significant wave height was intended to mathematically express the height estimated by a "trained observer". It is commonly used as a measure of the height of ocean waves. Time domain def ...

Sea Waves
In fluid dynamics, a wind wave, water wave, or wind-generated water wave, is a surface wave that occurs on the free surface of bodies of water as a result from the wind blowing over the water surface. The contact distance in the direction of the wind is known as the ''fetch''. Waves in the oceans can travel thousands of kilometers before reaching land. Wind waves on Earth range in size from small ripples, to waves over high, being limited by wind speed, duration, fetch, and water depth. When directly generated and affected by local wind, a wind wave system is called a wind sea. Wind waves will travel in a great circle route after being generated – curving slightly left in the southern hemisphere and slightly right in the northern hemisphere. After moving out of the area of fetch, wind waves are called '' swells'' and can travel thousands of kilometers. A noteworthy example of this is waves generated south of Tasmania during heavy winds that will travel across the Pacif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Company Rule In India
Company rule in India (sometimes, Company ''Raj'', from hi, rāj, lit=rule) refers to the rule of the British East India Company on the Indian subcontinent. This is variously taken to have commenced in 1757, after the Battle of Plassey, when the Nawab of Bengal was defeated and replaced with another individual who had the support of the East India Company; or in 1765, when the Company was granted the ''diwani'', or the right to collect revenue, in Bengal and Bihar; or in 1773, when the Company abolished local rule (Nizamat) and established a capital in Calcutta, appointed its first Governor-General, Warren Hastings, and became directly involved in governance. The rule lasted until 1858, when, after the Indian Rebellion of 1857 and consequently of the Government of India Act 1858, the British government assumed the task of directly administering India in the new British Raj. Expansion and territory The English East India Company ("the Company") was founded in 1600, as ''The Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
