1. THE HYDROLOGIC CYCLE

3. Processes of the Hydrologic Cycle
Evaporation: Process in which liquid water changes into water vapor.
During evaporation energy is absorbed by water molecules.

5. Condensation: Process in which water vapor changes into liquid water.
During condensation energy is released by water molecules.

7. Precipitation: Process in which water returns or falls to earth’s surface.
Examples are rain, snow, sleet and hail.

8. Runoff: water (precipitation) collects on Earth’s surface and runs downhill to streams, rivers, lakes and oceans.

9. Related Terms
Transpiration: water released by plants and evaporates.

10. Related Terms
Groundwater: water collect and flowing beneath the ground.
Aquifer: underground layer of permeable rock where water exist.
Contamination: pollution and/or chemicals in water

14. Water Cycle Questions
1. Why are the water droplets on the baggies clear?
2. Does the Earth have more or less water on it than 1000 years ago?
3. Clouds are examples of what?
4. Where is water released in the water cycle?
