Questions Related to rain: where does it come from

The freshwater stored in the ground is much more than that present in the rivers and lakes of the world.

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. True

  2. False

Show answer
Correct Option: A
Explanation:
  • Groundwater is the water found underground in the cracks and spaces in soil, sand, and rock. It is stored in and moves slowly through geologic formations of soil, sand, and rocks called aquifers.
  • Groundwater is the source of about 33 % of the water that county and city water departments supply to households and businesses (public supply).
  • Hence The freshwater stored in the ground is much more than that present in the rivers and lakes of the world is a true statement.
  • So, the correct answer is 'True'.

The process by which water from the surface of the earth moves to the atmosphere is:

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. cooling.

  2. distillation.

  3. evaporation.

  4. None of the above.

Show answer
Correct Option: C
Explanation:

The process by which water from the surface of the earth moves to the atmosphere is evaporation.

95% of the Earths water is stored in its:

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. glaciers

  2. oceans

  3. rivers

  4. ponds

Show answer
Correct Option: B
Explanation:

95% of the Earth's water is stored in its oceans, from where the water cycle starts. 

In water cycle, the maximum vaporization takes place:

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. from oceans

  2. from rivers

  3. from streams

  4. from plants

Show answer
Correct Option: A
Explanation:

86% of global evaporation occurs from the ocean due to its large surface area which directly comes in contact with sun rays and gives maximum vaporisation.


Hence, option A is correct.

Which of the following is not naturally occurring form of water?

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. Solid

  2. Liquid

  3. Vapour

  4. Semi-solid

Show answer
Correct Option: D
Explanation:

Water exists in liquid form upto  $100^0$C , at 100$^0$C it exists as vapour and at 4$^0$C it exists in solid form  as ice. So water exists in all the states or forms except semisolid, jelly state

So, the correct answer is 'Semi-solid'

Water is an extremely stable ____________.

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. atom

  2. element

  3. mixture

  4. compound

Show answer
Correct Option: D
Explanation:

Water is a stable compound. Components made up of two or more elements is called a compound. Water is made up of two elements namely hydrogen and oxygen.

Water produces hydrogen and oxygen in the ratio of :

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. 1:1

  2. 2:1

  3. 1:2

  4. 2:3

Show answer
Correct Option: B
Explanation:

Water molecular formula is $H _2O$. Water has 2 hydrogen and one oxygen atom. So it produces hydrogen and oxygen in the ratio 2:1.

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'.

Water heats up ___________ and cools off ___________ than land.

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. More quickly, more quickly

  2. More quickly, more slowly

  3. More slowly, more quickly

  4. More slowly, more slowly

Show answer
Correct Option: D
