Two thirds of our planet is covered with water.
Much of the water is found in lakes, rivers, and oceans. Water
exists on our earth in three forms: solid, liquid, and gas. The
water in lakes, rivers, and oceans is in liquid form. However, every
day some of this liquid turns to gas. As the sun shines, some of the
water evaporates. Evaporation means turning from water to
water vapor.
Evaporation
What happens to the water vapor in the air? Some
of it mixes with the air near the ground. Some of it rises into the
sky where the air is cooler. In this cooler area, the water vapor
turns back into little droplets of water. This is called condensation.
The droplets of water form clouds. As the water droplets get larger
and heavy they fall from the clouds as rain. Or if it is cold
enough, snow. This is called precipitation. Rain and
snow are the most common forms of precipitation.
Precipitation
Evaporation, condensation, and precipitation form
what is called The Water Cycle. The Water Cycle never
stops. It goes on and on. It happens over and over again.
