Water Cycle

Water Cycle


3. Water on Earth moves between the oceans and land through the processes of evapo­ration and condensation. As a basis for understanding this concept:

a. Students know most of Earth’s water is present as salt water in the oceans, which cover most of Earth’s surface.
b. Students know when liquid water evaporates, it turns into water vapor in the air and can reappear as a liquid when cooled or as a solid if cooled below the freezing point of water.
c. Students know water vapor in the air moves from one place to another and can form fog or clouds, which are tiny droplets of water or ice, and can fall to Earth as rain, hail, sleet, or snow.

This tutorial is designed for fifth grade students.
