The water cycle

2. What is the Water Cycle? • Evaporation • Condensation • Precipitation • Infiltration • Collection

3. Evaporation Evaporation is where water changes to a liquid, a gas or vapor. Water is transferred from the surface to the atmosphere through evaporation, the process by which water changes from a liquid to a gas. Approximately 80% of all evaporation is from the oceans, with the remaining 20% coming from inland water and vegetation.

4. Condensation Condensation is the change of water from its gaseous form (water vapor) into liquid water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.

5. Precipitation Rain, snow, sleet, or hail that falls to the ground. When clouds become very heavy with condensed water, the water is released in the form of rain, hail or snow.

6. Infiltration • Infiltration is the process by which water on the ground surface enters the soil. • Infiltration in the water cycle means the process where water on the surface goes into the soil. • After water infiltrates the soil, the water will become groundwater.

7. Collection The earth soaks up water and stores it in the ground. Water is temporarily stored in lakes, glaciers, underground, or living organisms. The water can move from these places by streams and rivers, returns to the oceans, is used by plants or animals or is evaporated directly back into the atmosphere.

8. Neat Facts About Water • 70% of Earth’s surface is covered by water • 0.001% of Earth’s water is found in the atmosphere • constant movement of water from Earth to the atmosphere and back to Earth; water evaporates, condenses to form clouds, and falls to Earth as precipitation The Water Cycle
