The Water Cylce
This set correlates with 4th grade science.
| Term | Definition |
|---|---|
| the sun | the source of the heat energy that drives the water cycle |
| ways that water changes state | evaporation, precipitation, and condensation |
| ways to change the state of water | addition or removal of heat |
| when heat energy is added to liquid water | Water changes into water vapor gas and rises through the process of evaporation from water on the Earth’s surface in rivers, streams, lakes, and oceans. |
| when heat energy is removed from water vapor | Water vapor condenses back into liquid water droplets that cling to dust particles in the air to form clouds. These water droplets may cling to solid surfaces near the ground to form frost or dew depending upon the temperature |
| precipitation | when water droplets in the air become too heavy and fall as a result of gravity |
| different forms of precipitation | rain, sleet, snow, hail (type depends on the temperature and weather conditions under which it forms) |
| once precipitation reaches the ground | gravity causes water to flow downhill through rivers and streams into ponds, lakes, and oceans |
