  1. Evaporation, condensation, precipitation

  2. Condensation, precipitation, evaporation

  3. Evaporation, precipitation, condensation

  4. Precipitation, evaporation, condensation

Show answer
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

Show answer
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

Show answer
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

Show answer
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
