Oceans - Question and Answer

What is the largest and deepest ocean of the world?  


Indian Ocean
Pacific Ocean
Atlantic Ocean
Arctic Ocean

Answer:

The Pacific Ocean is the largest and deepest of the world ocean basins. Covering approximately 59 million square miles and containing more than half of the free water on Earth, the Pacific is by far the largest of the world's ocean basins. All of the world's continents could fit into the Pacific basin.

The Mariana Trench or Marianas Trench is the deepest part of the world's oceans.It is located in the western Pacific Ocean, an average of 200 kilometres (124 mi) to the east of the Mariana Islands, in the Western Pacific East of Philippines. It is a crescent-shaped scar in the Earth's crust, and measures about 2,550 km (1,580 mi) long and 69 km (43 mi) wide on average. It reaches a maximum-known depth of 10,994 metres (36,070 ft) (± 40 metres [130 ft]) at a small slot-shaped valley in its floor known as the Challenger Deep, at its southern end,although some unrepeated measurements place the deepest portion at 11,034 metres (36,201 ft).If Mount Everest were dropped into the trench at this point, its peak would still be over 1.6 kilometres (1 mi) underwater.In 2009, Marianas Trench was established as a United States National Monument.

At the bottom of the trench the water column above exerts a pressure of 1,086 bars (15,750 psi), more than 1,000 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%, so that 95 litres of water under the pressure of the Challenger Deep would contain the same mass as 100 litres at the surface. The temperature at the top is 1 to 40C (34 to 390 F).

Suez Canal was nationalized in the year of  


1954
1955
1956
1957

Answer:

After World War II, Egypt pressed for evacuation of British troops from the Suez Canal Zone, and in July 1956 President Nasser nationalized the canal, hoping to charge tolls that would pay for construction of a massive dam on the Nile River. In response, Israel invaded in late October, and British and French troops landed in early November, occupying the canal zone. Under Soviet, U.S., and U.N. pressure, Britain and France withdrew in December, and Israeli forces departed in March 1957. That month, Egypt took control of the canal and reopened it to commercial shipping.

The land near which of the following is considered the lowest point on land on earth?  


Caspian Sea
Dead Sea
Black Sea
Salton Sea

Answer:

The Dead Sea, is a salt lake bordered by Jordan to the east and Israel and Palestine to the west. Its surface and shores are 430.5 metres (1,412 ft) below sea level, Earth's lowest elevation on land. The Dead Sea is 304 m (997 ft) deep, the deepest hypersaline lake in the world. With a salinity of 342 g/kg, or 34.2%, (in 2011), it is 9.6 times as salty as the ocean, and one of the world's saltiest bodies of water. This salinity makes for a harsh environment in which plants and animals cannot flourish, hence its name. The Dead Sea is 50 kilometres (31 mi) long and 15 kilometres (9 mi) wide at its widest point. It lies in the Jordan Rift Valley and its main tributary is the Jordan River.
