Tsunamis generally take birth in ____________.

geography ocean currents movements of ocean water movements of ocean and sea water oceanic circulations

  1. The ocean deep

  2. The deep sea plain

  3. The continental shelf

  4. The continental slope

Show answer
Correct Option: D
Explanation:

The tsunami height on the continental shelf is lower for steeper slope in comparison to flatter slope. This shows that, as the continental slope becomes flatter, more energy is transmitted to the shelf and higher tsunami height is observed.

Choose the odd one out.

geography ocean currents movements of ocean water movements of ocean and sea water oceanic circulations

  1. Brazil Current

  2. California Current

  3. Gulf stream

  4. Kuro Siwo Current

Show answer
Correct Option: B
Explanation:

All stream currents are westerly bound currents while California currents are easterly bound currents

Brazil current is the western boundary current of the South Atlantic subtropical gyre. It transports warm water polewards. Near 22 S, the Brazil current splits; one component flows eastward and the other component hugs the coast and flows toward the southwest and interacts with the colder Malvinas Current.

The Gulf Stream, together with its northern extension the North Atlantic Drift is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and stretches to the tip of Florida, and follows the eastern coastlines of the United States 

The Kuroshio is a north-flowing ocean current on the west side of the North Pacific Ocean. It is similar to the Gulf Stream in the North Atlantic and is part of the North Pacific ocean gyre. As the Gulf stream, it is a strong western boundary current.

California Current is a Pacific Ocean current that moves southward along the western coast of North America, beginning off southern British Columbia and ending off southern Baja California Peninsula. It is considered an Eastern boundary current due to the influence of the North American coastline on its course.

Fog is common around New Foundland coast because ______________.

geography ocean currents movements of ocean water movements of ocean and sea water oceanic circulations

  1. icebergs melt around the coast

  2. warm and cold currents meet

  3. rainfall is heavy

  4. high tides cause storms

Show answer
Correct Option: B
Explanation:

When cold and warm ocean current meet, the warm ocean current condenses after getting in contact with cold air and it results into fog.

Generally the warm ocean currents originate near __________.

geography ocean currents movements of ocean water movements of ocean and sea water oceanic circulations

  1. Poles

  2. Equator

  3. Lakes

  4. None of these

Show answer
Correct Option: B
Explanation:

Ocean currents may be cold, warm and hot. Warm ocean currents originate near the equator and move towards the poles or higher latitudes while cold currents originate near the poles or higher latitudes and move towards the tropics or lower latitude. 

Tides in the ocean will be highest when __________________.

  1. it is full Moon

  2. Moon is eclipsed

  3. Moon and Sun are pulling at right angles to the Earth

  4. Moon is in new phase

Show answer
Correct Option: D

  1. Currents are rivers in the sea

  2. The water moves forward and the currents are felt at the depth as well

  3. They are caused by the unequal temperature of equatorial and polar regions

  4. Generally there is scanty rainfall over the coastal areas where the warm currents flow

Show answer
Correct Option: D
