WHY DOES IT RAIN?

Why does it rain? 

"There are always tiny drops of water vapor in the air. Warm air has more water vapor than cold air, which is why it is often humid in the summer.

Warm air rises, and with it rise the water droplets. These tiny drops rise if cold air blows in. Mountains can also make them rise, which is why it rains a lot there. When the air holds lots of water droplets, clouds form. If a lot of water droplets gather in the clouds, the clouds become heavy. Gravity causes the water droplets to fall as rain."
