About how much water is recycled in the form of rains per year?

  1. 4.46 $\times 10^5$ gram per year
  2. 4.46 $\times 10^{10}$ gram per year
  3. 4.46 $\times 10^{20}$ gram per year
  4. 4.46 $\times 10^{30}$ gram per year

C Correct answer
Explanation

Water exists at the earth's surface as liquid, solid, and vapour. It is changing from one of those three states to another. The total amount of water near the surface of the earth stays almost the same through time. One of the most important steps in the water cycle involves evaporation of water from the ocean surface, transport in the form of water vapour to the continents by winds, and precipitation as rain or snow on the continents. The rainfall then runs off by way of streams, rivers, and groundwater back to the ocean. Almost 4.46 10^20 gram per year of water is recycled in the form of rains per year.

Therefore, the correct answer is option C.

Water remaining in the soil after a plant has permanently wilted is

  1. Hygroscopic water

  2. Ground water

  3. Gravitational water

  4. Capillary water
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Hygroscopic water is the water held tightly by the soil and cannot be taken up by plant roots because this water forms very thin films around soil particles and is not available to the plant. Thus the correct answer is option A.

The rain shadow effect is used to describe rainfall around certain mountain ranges. Choose the correct statement.

  1. The northern hemisphere and the southern hemisphere have the same prevailing winds

  2. Cool air can hold more moisture than warm air

  3. In the northern hemisphere, there is more rainfall on the eastern slopes

  4. You would expect deserts to form on the western side of mountain ranges in the northern hemisphere

  5. None of the above

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

An area with relatively little precipitation due to the presence of mountain range is called as rainshadow. This barrier causes the prevailing winds to lose their moisture on the windward side of the mountain ranges thereby causing the leeward side to be dry. The rain shadow effect, therefore, brings in rainfall to certain mountain ranges while its other side is generally a dry desert area. The prevailing wing or the  "trade winds" as they are called  are located at 30° North and 30° South latitudes. The trade winds which are present in the Northern Hemisphere come from the northeast, and those in the Southern Hemisphere come from the southeast. The "Westerly winds" are located 30 and 60 degrees latitudes, and, in contrast to the trade winds, originate from the southwest in the Northern Hemisphere and originate from the northwest in the Southern Hemisphere

Cyclic/frontal rainfall generally occurs

  1. All over the world

  2. Tropical areas

  3. Temperate areas

  4. Boundary of warm tropical air and cold polar air
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The frontal or the cyclonic rainfall occurs along the front. The front refers to an area where the cold polar air and the warm tropical air collide and do not mix. There develops a boundary called front. This is usually seen in the coastal areas. The condensation of the air along the front forms the clouds and precipitation occurs, called the frontal rain. When the warm air replaces the cold air, it is called warm front and it causes less intense rainfall over a large area. When the cold air replaces the warm air, it is called the cold front and it causes intense rainfall over a small area.

Hence, the correct answer is 'Boundary of warm tropical air and cold polar air'
