Question

For clouds to form, water vapor in the air must condense and change from a gas to a liquid. What must water molecules do as a part of this process?
A. come close together and stick to each other
B. escape into the surrounding air
C. connect to each other in a rigid structure
D. stop moving relative to each other

Answer 1

Cloud formation process :

1) Water on earth gets heated and evaporate into the atmosphere.

2) The water vapour on reaching a certain altitude condense to form water molecules.

3) These water molecules come close to each other to form clouds.
