The Water Cycle
|
Review the parts of the Water Cycle:
•Evaporation is when water heats up and changes into water vapor.
•Condensation is when water vapor cools and changes back into water on a surface.
•Precipitation is when water falls back to Earth as rain, snow, sleet or hail.

Describe and graph the amounts and percentages of
water and fresh water in various reservoirs to provide evidence about the
distribution of water on Earth.
ESS2.C:
The Roles of Water in Earth’s Surface Processes
Nearly all of Earth’s available water is in the ocean.
Most fresh water is in glaciers or underground; only a tiny fraction is in
streams, lakes, wetlands, and the atmosphere. (5-ESS2-2)
CA State Science Standards
3a. Students know most of Earth’s water is present as salt water in the oceans, which cover most of Earth’s surface.
3b. 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.
3c. 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. 3d. Students know that the amount of fresh water located in rivers, lakes, underground sources, and glaciers is limited and that its availability can be extended by recycling and decreasing the use of water.
