THE OCEANS AND THE SEAS - 5 - ANSWERS



1. C. Baltic Sea





Baltic Sea, an arm of the North Atlantic Ocean, extends northward from the latitude of southern Denmark almost to the Arctic Circle and separates the Scandinavian Peninsula from the rest of continental Europe. The many names for the sea attest to its strategic position as a meeting place of many countries. Proceeding clockwise from the west, the countries bounding the Baltic are Denmark, Sweden, Finland, Russia, Estonia, Latvia, Lithuania, Poland and Germany. The people of Sweden call it the "East Sea" while people of Estonia call it as "West Sea".





The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea–Baltic Canal and to the German Bight of the North Sea via the Kiel Canal, one of the world's busiest artificial waterways.







2. B. 200






An "Exclusive Economic Zone" (EEZ) is a sea zone prescribed by the 1982 United Nations Convention on the Law of the Sea (UNCLOS) over which a sovereign state has special rights regarding the exploration and use of marine resources, including energy production from water and wind. It stretches from the baseline out to 200 nautical miles (nmi) from its coast.

In colloquial usage, the term may include the continental shelf. The term does not include either the territorial sea or the continental shelf beyond the 200 nmi limit. The difference between the territorial sea (As per the UNCLOS, the territorial sea is a belt of coastal waters that extends from the baseline to 12 nautical miles) and the exclusive economic zone is that the first confers full sovereignty over the waters, whereas the second is merely a "sovereign right" which refers to the coastal state's rights below the surface of the sea.






3. B. Rodriguez Point






The "Rodrigues Triple Junction" (RTJ), also known as the "Central Indian [Ocean] Triple Junction" (CITJ) is a geologic triple junction in the southern Indian Ocean where three tectonic plates meet: "the African Plate", "the Indo-Australian Plate", and "the Antarctic Plate". The triple junction is named for the island of "Rodrigues" which lies 1,000 km (620 mi) north-west of it.



The boundaries of the three plates which meet at the "Rodrigues Triple Junction" are all oceanic spreading centers, making it an R-R-R (Ridge-Ridge-Ridge) type triple junction. They are: the "Central Indian Ridge" (CIR, between the African and Indo-Australian plates) with a spreading rate of 50 mm/yr; the "Southwest Indian Ridg"e (SWIR, between the African and Antarctic plates) 16 mm/yr; and the "Southeast Indian Ridge" (SEIR, between the Indo-Australian and Antarctic plates) 60 mm/yr.




4. A. Canada





Canada, the second-largest country in the world with a total area of 9,984,670 km2, has the longest coastline of all the countries in the world - a staggering 202,080 kilometres. The Canadian Arctic Archipelago, which consists of 36,563 islands, contributes to the total length of the coastline of Canada.


Indonesia, with a coastline measuring 54,716 kilometres has the second longest coastline in the world.






5. B. Drake Passage




"Drake Passage", deep waterway, 1,000 km wide, connecting the Atlantic and Pacific oceans between Cape Horn (the southernmost point of South America) and the South Shetland Islands, situated about 160 km north of the Antarctic Peninsula. The Drake Passage defines the zone of climatic transition separating the cool, humid, subpolar conditions of Tierra del Fuego (the southernmost tip of the South American mainland) and the frigid, polar regions of Antarctica.






Though bearing the name of the famous English seaman and global circumnavigator "Sir Francis Drake", the passage was first traversed in 1616 by a Flemish expedition led by "Willem Schouten". The Drake Passage played an important part in the trade of the 19th and early 20th centuries before the opening of the Panama Canal in 1914.
