Questions Related to sources of water and water cycle

Rainfall patterns depend on

evs sources of water and water cycle groundwater and depletion of water table rain: where does it come from availability and forms of water the water cycle

  1. The underground water table

  2. The number of water bodies in an area

  3. The density pattern of human population in an area

  4. The prevailing season in an area.

Show answer
Correct Option: B
Explanation:

Rainfall pattern will depend on number of water bodies in an area, as there will be large water bodies, (ocean, river) the rate of evaporation would be high, which will help to cause rain in the area.

More than 70% of world's fresh water is contained in

evs sources of water and water cycle groundwater and depletion of water table rain: where does it come from availability and forms of water the water cycle

  1. Antarctica

  2. Polar ice

  3. Glaciers and Mountains

  4. Greenland

Show answer
Correct Option: B
Explanation:
More than 70% of world's fresh water is contained in Polar ice. These polar ice are present in the form of two sheets in Antartica and Greenland.
So, the correct answer is 'Polar ice'.

  2. More quickly, more slowly

  3. More slowly, more quickly

  4. More slowly, more slowly

Show answer
Correct Option: D

  1. Acidity

  2. Pollutions

  3. Air pollution

  4. Water Pollutions

Show answer
Correct Option: A

  1. 1.3 mm/yr

  2. 1.8?mm/yr

  3. 1.7 mm/yr

  4. 1.9 mm/yr

Show answer
Correct Option: B

Water vapor is present in air only during the monsoon.

biology rain: where does it come from sources of water and water cycle availability and forms of water the water cycle

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

No, water vapor is present in the air during all seasons

The solid form of water is known as:

chemistry rain: where does it come from sources of water and water cycle availability and forms of water the water cycle

  1. fog

  2. dry ice

  3. ice

  4. snow

Show answer
Correct Option: C
Explanation:

The solid form of water is known as ice.

Evaporation is defined as:

chemistry rain: where does it come from sources of water and water cycle availability and forms of water the water cycle

  1. conversion of ice in water.

  2. conversion of water into water vapours.

  3. conversion of water vapours into the water.

  4. freezing of water into ice.

Show answer
Correct Option: B
Explanation:

When water is heated it absorbs energy and changes its state from liquid (water) to gas(water vapours). This process of converting water in vapours is known as vaporisation.

Which of the following processes is unsuitable for softening water possessing temporary hardness?

biology rain: where does it come from sources of water and water cycle availability and forms of water the water cycle

  1. Adding calcium hydroxide

  2. Filtration

  3. Boiling

  4. Distillation

Show answer
Correct Option: A
Explanation:

If you added calcium oxide to water, it would react and make calcium hydroxide. Calcium hydroxide is produced, however, when calcium oxide is mixed (or slaked) with water. Overall, nothing significant happens when you mic Ca(OH)2 with water, certainly no reaction occurs. So, the correct option is "A" (Adding calcium hydroxide).

Which of the following is the most important factor in balancing the amount of freshwater on earth?

evs rain: where does it come from sources of water and water cycle availability and forms of water the water cycle

  1. Water cycle

  2. Greenhouse effect

  3. Waste water treatment plant 

  4. Transpiration

Show answer
Correct Option: A
Explanation:

Water cycle is a continuous cycle in which water changes from water vapour in the atmosphere, through liquid water through condensation and precipitation and then back to water vapour through evaporation, transpiration and respiration. 

Among the given options, $A$ is the correct one.
