When water evaporates from land and different water bodies, it becomes water vapour. What happens to this water vapour as it rises higher in the atmosphere?

Options

Option A

It becomes warmer and expands, forming clouds.

Option B

It gets converted into oxygen due to atmospheric pressure.

Option C is correct

It cools down and condenses to form tiny droplets of water, leading to cloud formation.

Option D

It completely disappears into space due to lack of gravity.

Explanation

As water vapour rises higher in the atmosphere, it encounters cooler temperatures. Cold air has a lower capacity to hold moisture. Therefore, as the water vapour cools down, it undergoes condensation, changing from a gaseous state back into tiny liquid water droplets or ice crystals. These tiny droplets or crystals clump together around dust particles, forming clouds. This process is crucial for the water cycle and ultimately leads to precipitation. Option C accurately describes this phenomenon. The other options are scientifically incorrect.
