Deepest Sea : Caribbean Sea

The Caribbean Sea is a sea of the Atlantic Ocean situated in the tropics of the Western hemisphere. It is bounded by Mexico and Central America to the west and southwest, to the north by the Greater Antilles, and to the east by the Lesser Antilles.

The entire area of the Caribbean Sea, the numerous islands of the West Indies, and adjacent coasts, are collectively known as the Caribbean. The Caribbean Sea is one of the largest salt water seas and has an area of about 2,754,000 km² (1,063,000 sq. mi.). The sea's deepest point is the Cayman Trough, between the Cayman Islands and Jamaica, at 7,686 m (25,220 ft) below sea level. The Caribbean coastline has many gulfs and bays: the Gulf of Gonâve, Gulf of Venezuela, Gulf of Darién,Golfo de los Mosquitos, Gulf of Paria and Gulf of Honduras.

The name "Caribbean" is derived from the Caribs, one of the dominant American Indian groups in the region at the time of European contact during the late 15th century. After the discovery of the West Indies by Christopher Columbus in 1492, the Spanish term Antillas was assigned to the lands; stemming from this, "Sea of the Antilles" is a common alternative name for the Caribbean Sea in various European languages. During the first century of development, the Spanish dominance was undisputed.

Deepest Ocean: Indian Ocean

The Indian Ocean is the third largest of the world's oceanic divisions, covering approximately 20% of the water on the Earth's surface. It is bounded on the north by the Indian subcontinent; on the west by East Africa; on the east by Indochina, the Sunda Islands, and Australia; and on the south by the Southern Ocean (or, depending on definition, by Antarctica). The ocean is named after the geographic location called India.

As one component of the interconnected global ocean, the Indian Ocean is delineated from the Atlantic Ocean by the 20° east meridian running south from Cape Agulhas, and from the Pacific by the meridian of 146°55' east.The northernmost extent of the Indian Ocean is approximately 30° north in the Persian Gulf. The Indian Ocean has asymmetric ocean circulation^{[citation needed]}. This ocean is nearly 10,000 kilometres (6,200 mi) wide at the southern tips of Africa and Australia; its area is 73,556,000 square kilometres (28,350,000 sq mi), including the Red Sea and the Persian Gulf.

The ocean's volume is estimated to be 292,131,000 cubic kilometres (70,086,000 mi³).Small islands dot the continental rims. Island nations within the ocean are Madagascar, the world's fourth largest island; Reunion Island;Comoros; Seychelles; Maldives; Mauritius; and Sri Lanka. The archipelago of Indonesia borders the ocean on the east.

Sea: Andaman Sea

The Andaman Sea or Burma Sea is a body of water to the southeast of the Bay of Bengal, south of Burma, west of Thailand and east of the Andaman Islands, India; it is part of the Indian Ocean.

The sea has been traditionally used for fishery and transportation of goods between the coastal countries and its coral reefs and islands are popular tourist destinations. The fishery and tourist infrastructure has been severely damaged by the 2004 Indian Ocean earthquake and tsunami.

The average depth of the sea is about 1,000 meters (3,300 ft). The northern and eastern parts are shallower than 180 meters (600 ft) due to the silt deposited by the Irrawaddy River. This major river flows into the sea from the north through Burma. The western and central areas are 900–3,000 meters deep (3,000–10,000 ft). Less than 5% of the sea is deeper than 3,000 meters (10,000 ft), and in a system of submarine valleys east of the Andaman-Nicobar Ridge, the depth exceeds 4,000 meters (13,200 ft). The sea floor is covered with pebbles, gravel and sand.

Ocean: Atlantic Ocean

The Atlantic Ocean is the second largest of the world's five oceans (after the Pacific Ocean, but larger than the Indian Ocean, Southern Ocean, and Arctic Ocean). The Kiel Canal (Germany), Oresund (Denmark-Sweden), Bosporus (Turkey), Strait of Gibraltar (Morocco-Spain), and the Saint Lawrence Seaway (Canada-US) are important strategic access waterways. The decision by the International Hydrographic Organization in the spring of 2000 to delimit a fifth world ocean, the Southern Ocean, removed the portion of the Atlantic Ocean south of 60 degrees south latitude.

The Atlantic Ocean is essentially an S-shaped north-south channel, extending from the Arctic Ocean in the north to the Antarctic continent in the south and situated between the eastern coast of the American continents and the western coasts of Europe and Africa. The Atlantic Ocean proper has a surface area of about 82 million sq km (about 31,660,000 sq mi). Including its marginal seas-the Gulf of Mexico-Caribbean Sea, the Arctic Ocean, and the North, Baltic, Mediterranean, and Black seas-the total area is about 106,190,000 sq km (about 41 million sq mi).

Longest Coastline: Canada

Canada ( /ˈkænədə/) is a North American country consisting of ten provinces and three territories. Located in the northern part of the continent, it extends from the Atlantic Ocean in the east to the Pacific Ocean in the west and northward into the Arctic Ocean. It is the world's second largest country by total area. Canada's common border with the United States to the south and northwest is the longest in the world.


The land that is now Canada was inhabited for millennia by various groups of Aboriginal peoples. Beginning in the late 15th century, British and French expeditions explored, and later settled, along the Atlantic coast. France ceded nearly all of its colonies in North America in 1763 after the Seven Years' War. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federaldominion of four provinces. This began an accretion of provinces and territories and a process of increasing autonomy from the United Kingdom. This widening autonomy was highlighted by the Statute of Westminster 1931 and culminated in the Canada Act 1982, which severed the vestiges of legal dependence on the British parliament.


Canada is a federal state that is governed as aparliamentary democracy and a constitutional monarchy with Queen Elizabeth II as its head of state. It is a bilingual nation with both English and French as official languages at the federal level. One of the world's highly developed countries, Canada has a diversified economy that is reliant upon its abundant natural resources and upon trade—particularly with the United States, with which Canada has had a long and complex relationship.


The coastline of Canada, including all its islands, is more than six times as long as the distance round the Earth at the Equator [40,076km]. Greenland is not in this list as it is part of Denmark, not a separate country, but its coastline measures 44,087km.

Longest Glacier: Lambert Fisher

Fisher Glacier is a prominent western tributary to the Lambert Glacier, about 100 miles (160 km) long, flowing east past the north sides of Mount Menzies and Mount Rubin and joining the main stream of the Lambert Glacier just east of Mount Stinear. Sighted from ANARE (Australian National Antarctic Research Expeditions) aircraft by K.B. Mather in 1957. 


During the last Ice Age, more than 30 percent of the Earth's surface was covered by glaciers- frozen rivers of ice that move very slowly. Even today, as much as 10 percent is covered with glaciers. The Lambert Fisher Glacier is the longest in the world and was only discovered in 1956. The longest glacier in North America is the Hubbard Glacier, Alaska, which measures 146km. The longest in Europe is the Aletsch Glacier, Switzerland, at 35km.

The Great Lake : Superior

Lake Superior  is the largest of the five Great Lakes of North America. It is bounded to the north by the Canadian province of Ontario and the U.S. state of Minnesota, and to the south by the U.S. states of Wisconsin and Michigan. It is the largest freshwater lakein the world by surface area if Lake Michigan-Huron is counted as two lakes and is the world's third-largest freshwater lake by volume.


The Ojibwe call the lake Gichigami, meaning "big water." Henry Wadsworth Longfellow wrote the name as "Gitche Gumee" in The Song of Hiawatha, as did Gordon Lightfoot in his song, "The Wreck of the Edmund Fitzgerald". "The first French explorers approaching the great inland sea by way of the Ottawa River and Lake Huron during the 17th century referred to their discovery as le lac superieur. Properly translated, the expression means "Upper Lake," that is, the lake above Lake Huron. The lake was also called Lac Tracy by 17th century Jesuit missionaries." The English, upon taking control of the region from the French in the 1760's, following the French and Indian War, anglicized the lake's name to Superior, "on account of its being superior in magnitude to any of the lakes on that vast continent."
