The Water Cycle
Clouds form when there is water in the sky. Water from the ground gets pulled back up into the sky. This is called evaporation.
Evaporation is when a liquid changes to a gas form. Water becomes vapor. This happens faster in warmer places. For example, think about a cup of water standing on a table. It might take a week or two for all the water to evaporate. But you could boil the same amount of water in a pot on the stove. It would turn to vapor in minutes.
Plants get water from the soil. The water moves from the roots up to the stems. It winds up in the leaves. From the leaves, some of the water evaporates into the air. Where there are many plants and trees, like in forests, a large amount of water transpires into the air.
When the water cools, it becomes clouds. This is called condensation. Clouds are made of tiny droplets of water. When they gather in the sky, you can see the droplets in the form of clouds.
