Hydrosphere MCQ Question and Answer | Geography MCQ Question

Statement 1 is incorrect.
Ocean currents are not just slow-surface movements; they encompass the entire water column and include both surface and deep currents.

Statement 2 is correct.
Ocean currents play a significant role in redistributing heat around the Earth, helping to regulate the planet's heat balance.

Statement 3 is correct.
Prevailing winds are a major driving force behind the movement of ocean currents. Wind patterns at the surface of the ocean create friction and transfer energy to the water, setting the currents in motion.

Statement 4 is correct.
The configuration of the ocean, including factors such as the shape of coastlines, the presence of continents, and the location of underwater features, can influence the direction and behavior of ocean currents.

Therefore, the correct options are 2, 3, and 4 (Option B).

The following sequences of ocean trenches that is correct in terms of the ascending order of their depths are New Herbides Trench - Aleutian Trench - Mindanao Trench. New Hebrides Trench reaches maximum depths of some 25,000 feet (7,600 metres) or more, the deepest soundings in the whole Coral Sea region. The Aleutian Trench reaches a maximum depth of 26,604 feet (8,109 metres) at about 51° N, 178° W. The Mindanao trench reaches one of the greatest depths in the ocean, third only to the Mariana trench and the Tonga trench. Its deepest point is known as Galathea Depth and reaches 10,540 meters (34,580 ft) or (5,760 fathoms).

The Amazon is considered the world's largest river by volume, but scientists have believed it is slightly shorter than Africa's Nile. The Brazilian scientists' 14-day expedition extended the Amazon's length by about 176 miles (284 kilometers), making it 65 miles (105 kilometers) longer than the Nile.

Along the coasts salinity is lowered. Salinity in the oceans is constant but is more variable along the coast where seawater is diluted with freshwater from runoff or from the emptying of rivers.

Lake Titicaca is called as 'Honeymoon Lake'. Lake Titicaca is famous among honeymoon couples due to its scenic features. Situated in Andes range it marks border of Bolivia & Peru. It is large & deep lake. The largest in South America.

The ocean currents and winds transport the heat from the lower latitudes near the equator to higher latitudes near the poles. The transfer of heat energy within the atmosphere, hydrosphere, and the Earth's surface and interior occurs as a result of radiation, convection, and conduction. Ocean currents play a significant role in transferring this heat toward the poles.

Black Sea will likely to be flown over by Mr. X.

Tsunami is a Japanese word meaning harbour wave. Although both are sea waves, a tsunami and a tidal wave are two different and unrelated phenomena. A tidal wave is a shallow water wave caused by the gravitational interactions between the Sun, Moon, and Earth. ("Tidal wave" was used in earlier times to describe what we now call a tsunami.)

The principal origin of those icebergs that reach the North Atlantic Ocean are the 100 or so major tidewater glaciers of West Coast Greenland.

Ocean currents are warm off the west coast of continents within the tropics. They move clockwise in the oceans of the Northern Hemisphere.
