A Correct answer
Explanation

The process by which water continually changes its form and circulates between oceans, atmosphere and the land is called the water cycle.

The water cycle, also called the hydrological cycle, involves the continuous circulation of water in the Earth-atmosphere system. Of the many processes involved in the water cycle, the most important are evaporation, transpiration, condensation, precipitation, and runoff.

Generally the warm ocean currents originate near __________.

  1. Poles

  2. Equator

  3. None of these

  4. Both A and B

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The warm ocean currents originate near the equator and move towards the poles. The cold currents carry water from polar or higher latitudes to tropical or lower latitudes.
Warm ocean currents flow away from the equatorial region on the western side of ocean basins. The Gulf Stream in the North Atlantic and the Kuroshio Current in the North Pacific are examples of warm currents.

Even though 70% of the earth's surface is covered by water, the water available for human use through rivers, lakes and tanks is only _______.

  1. 3%

  2. 30%

  3. 2.3%

  4. 0.03%

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

While 70% of the Earth is water, most is saline ocean water. Only about 2.5% to 3% is fresh water, and of that, only a tiny fraction (roughly 0.03%) is accessible in rivers, lakes, and tanks for human use.

Land and Sea breezes are basically caused by ______________.

  1. Temperature variations in summer and winter

  2. Differential heating between land and sea

  3. Convergence of warm and cold currents

  4. None of these

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Land and Sea breezes are basically caused by differential heating between land and sea.

During the day, the wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse. The air over the ocean is now warmer than the air over the land. So the pressure over water is low and high on land. So we have a land breeze blowing from land to sea.
