Question

how is rainfall caused

Answer 1

Why does it rain? When water on the Earth's surface is heated by the Sun, it evaporates and turns into water vapour which rises into the air. When the air cools it condenses around some dust or other particles in the air, called condensation nuclei. These small droplets then become visible as clouds.

Answer 2

Answer:

Explanation:As the hot air rises it reaches high in the atmosphere where it cools down due to the pressure of the low temperature there.

Thus, the water pressent in he form of water vapour condensed into tiny droplets of water or crystals of ice

When the water become so heavy that the air cannot hold them

Hence,they fall down as rainfall.
