Question

What is rainfall when points goes uper

Answer 1

When the humid air rises up,it cools and condensation of water vapour takes place.The water vapour is deposited on hydroscopic particles and turned into water particles.These are known as cloud particles.The cloud particles float in the air and clouds are formed.If these particles come close to one another,they may coalesce into bigger particles.When their size becomes so large that their weight is more than the upthrust of air,the particles will fall down in the form of Rain.
