Questions Related to the lithosphere and the hydrosphere

Which of the following plays a very important role in causing rainfall?

  1. Factories

  2. Vehicles

  3. Plants

  4. None of the above


Correct Option: C
Explanation:

Transpiration is the process in which plants lose water as water vapor during photosynthesis. This water is added to the moisture in air saturating it and hence generating rainfall. Thus the correct answer is option C.

Water cycles through the biosphere in all of the following processes except     

  1. Precipitation

  2. Condensation

  3. Transpiration

  4. Decomposition

  5. Runoff


Correct Option: D
Explanation:
A. When the water vapour in the atmosphere condenses and fall in the form of rain, hail, snow etc., it is called precipitation.
B. Condensation is the conversion of a gas into liquid when the temperature is lowered down.
C. Transpiration is the loss of water in vapour form from the surface of leaves through minute pores called stomata.
D. Decomposition is the process of breakdown of complex organic materials into simpler ones.
E. Runoff is the overflow or the flow of excess water over the earth's surface from any water source.
Hence, water cycles through the biosphere in all of the given processes except decomposition.
So, the correct answer is 'Decomposition'.

In the water cycle, the process by which water is returned to the atmosphere is known as 

  1. Runoff

  2. Condensation

  3. Evaporation

  4. Precipitation

  5. Photosynthesis


Correct Option: C,E
Explanation:

Evaporation and photosynthesis are two process through which water is returned to the atmosphere during water cycle.

So, the correct answer is 'Evaporation and Photosynthesis'

Which of the following processes represents X?
River -> X -> Clouds

  1. Respiration

  2. Transpiration

  3. Combustion

  4. Evaporation


Correct Option: D
Explanation:

In the given figure, X is evaporation. Evaporation is the process of conversion of water into vapour. Water vapour rises up into the atmosphere and cools down to form clouds.

So, the correct answer is option D.

The largest part of hydrosphere is 

  1. Pacific ocean

  2. Atlantic ocean

  3. Indian ocean

  4. None of the above


Correct Option: A

Which of the following explains drought?

  1. Low rainfall than requirement

  2. High rainfall than requirement

  3. Low pressure in atmosphere

  4. High pressure in atmosphere


Correct Option: A

Which of the following are included in hydrosphere?

  1. Liquid and frozen surface waters

  2. Groundwater held in soil and rock

  3. Atmospheric water vapor

  4. All of the above


Correct Option: D
Explanation:

The hydrosphere is the total amount of water present on the planet which includes the surface water, underground water and in the air (Atmosphere) as water vapor. Hydrosphere can be liquid, ice or vapor. 

So the correct option is 'all of the above'.

The part of earth comprising water is called an

  1. atmosphere

  2. hydrosphere

  3. lithosphere

  4. None of the above


Correct Option: B
Explanation:
A. The atmosphere is the layer of gases which surround the earth.
B. Hydrosphere is the amount of water present on earth.
C. The lithosphere is the outer and rigid part of the earth that consists of crust and mantle.
So, the correct answer is 'Hydrosphere'.

Water is required in our daily life; as per United Nations what is the minimum amount of amount required for a single person to maintain proper hygiene?

  1. 50 liters/day

  2. 20 liters/day

  3. 65 liters/day

  4. 100 liters/ day


Correct Option: A
Explanation:


Amount of water recommended by the United Nations for drinking, washing, cooking and maintaining proper hygiene is a minimum of 50 liters per person per day.

So, the correct answer is '50 liters/day' 

The water is bad conductor of electricity.

  1. True

  2. False


Correct Option: B
Explanation:

Distilled water is a bad conductor of electricity as it is electrically neutral. However, tap water is a good conductor of electricity as it may contain some impurities and therefore, the ions flow resulting in the conductivity. So, this statement is "false".
