More about Rain:

                   Rain is droplets of water that drop down from clouds. Heat from the Sun turns moisture from plants and leaves, as well as oceans, lakes, and rivers, into water vapour, which evaporates into the air. This vapour rises, cools, and changes into small water droplets, which form clouds. The water droplets in the clouds join together to form larger drops.

When the water droplets get too large and weighty, they fall as rain. Big, heavy droplets falling to the earth are called rain, and small droplets are called drizzle. They are dark because they are full of big water droplets that hurdle out the light from the Sun.
