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

  1. Transpiration

  2. Evaporation

  3. Condensation

  4. Precipitation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Evaporation is the phase transition where liquid water gains enough energy to become water vapor. Transpiration is a specific biological form of evaporation from plants, while condensation is the reverse process.

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
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Condensation occurs when water vapor cools down and loses energy, transitioning back into liquid droplets. Rapid cooling of air reduces its capacity to hold water vapor, forcing it to condense.

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
Reveal answer Fill a bubble to check yourself
A Correct answer
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
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The water cycle is essential for maintaining life on Earth. It facilitates the recharging of groundwater aquifers, replenishes surface water bodies, and ensures the distribution of freshwater through rainfall.

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
Reveal answer Fill a bubble to check yourself
C Correct answer
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
Reveal answer Fill a bubble to check yourself
B Correct answer
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
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Evaporation (mixing) fog occurs when warm rain falls through a layer of colder air. The evaporation of the rain adds moisture to the cold air, which then saturates and condenses into fog.

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

  1. Freezing

  2. Condensation

  3. Sublimation

  4. Evaporation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The transition from liquid water to water vapor is defined as evaporation. Sublimation is the transition from solid to gas, while condensation is gas to liquid.
