No matter what shape or size they are, clouds are essential to life on Earth. During the day they help protect us from the sun's intense heat. At night they act as a blanket to keep us from getting too cold. They also provide precipitation and signal weather changes and patterns.

Do clouds have a purpose?

What do clouds give us?

Clouds are important for many reasons. Precipitation, like rain or snow, is one of those reasons. At night, clouds reflect heat back to the surface and keep it warmer. During the day, clouds can shade us from the sun and keep Earth cooler.
