Questions Related to bio-geo chemical cycles in nature

Water evaporates into air from oceans, rivers and lakes but not from the soil.

  1. True

  2. False


Correct Option: B
Explanation:

Soil also contains water, so evaporation also takes place from the soil.

The process by which water change into water vapour is called as

  1. Transpiration

  2. Evaporation

  3. Condensation

  4. Precipitation


Correct Option: B

Which of the following process in the water cycle takes place due to rapid cooling of air?

  1. Condensation

  2. Evaporation

  3. Precipitation

  4. None of the above


Correct Option: A

Identify the correct sequence of stages in the water cycle.

  1. Evaporation, condensation, precipitation

  2. Condensation, precipitation, evaporation

  3. Evaporation, precipitation, condensation

  4. Precipitation, evaporation, condensation


Correct Option: A
Explanation:
Answer is option A i.e. "Evaporation, condensation, precipitation"
There are 3 main stages involved in water cycle i.e. evaporation, condensation, precipitation and runoff. The water cycle starts with evaporation followed by condensation where water vapor converts int liquid water and finally precipitation where liquid water falls from sky in form of rains, snow, hail, etc.

Which of the following is an advantage of occurrence of the water cycle? 

  1. Recharging of ground water

  2. Recharging of water bodies

  3. Sufficient rainfall

  4. All of the above


Correct Option: D

Which of the following process is responsible for the smoke-like vapour which comes out of the mouth in winter?

  1. Precipitation

  2. Evaporation

  3. Condensation

  4. None of the above


Correct Option: C
Explanation:
  • When you exhale when it's cold outside, the water vapour in your breath condenses into lots of tiny droplets of liquid water and ice (solid water) that you can see in the air as a cloud, similar to fog which appears smoke like. This process is called condensation.
  • Hence Condensation process is responsible for the smoke-like vapour which comes out of the mouth in winter.
  • So, the correct answer is 'Condensation'.

The water vapour which enters into air to form clouds in the sky are obtained by which of the following process?

  1. Condensation

  2. Evaporation

  3. Precipitation

  4. None of the above


Correct Option: B
Explanation:
  • Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.
  • By the process of evaporation, the water vapour enters into the air to form clouds in the sky. 
  • The water vapour in the air condenses to form tiny water droplets which are the basis of clouds.
  • Hence the process by which water vapour enters into the air to form clouds in the sky is Evaporation.
  • So, the correct answer is 'Evaporation'.

Fog that most often forms as warm rain falls into a cold layer of surface air is called:

  1. Radiation fog

  2. Evaporation (mixing) fog

  3. Advection fog

  4. Upslope fog


Correct Option: B

When water changes from a liquid to a vapor, we call this process:

  1. Freezing

  2. Condensation

  3. Sublimation

  4. Evaporation


Correct Option: D
