1. The Water Cycle http://ga.water.usgs.gov/edu/graphics/watercyclesummary.jpg

2. What is the Water Cycle? Controls the distribution of Earth’s water Circulates through four spheres of Earth Has no starting point Earth’s water is always in movement Water is always changing states

3. Parts of the Water Cycle Evaporation Transpiration Condensation Cloud Formation Precipitation Infiltration Surface Runoff Groundwater Absorption

4. Evaporation Change from liquid to gas (vapor) Includes vaporization from: Water surfaces Land surfaces Snow fields Not vaporization from leaf surfaces http://www.kidzone.ws/water/

5. Team Time Draw the process of evaporation.

6. Transpiration Water absorbed by plants is evaporated Water is absorbed through roots Evaporated from the plant surface (leaves) http://ga.water.usgs.gov/edu/pictures/wctranspirationleafsoil.jpg

7. Condensation Change from gas to liquid Opposite of evaporation Example of condensation: Cold glass, hot day http://farm1.static.flickr.com/215/521585824_54ed44d010_m.jpg

8. Team Time Draw the process of condensation.

9. Cloud Formation Water vapor joining with dust particles All clouds contain water vapors Rarely see clouds in the desert http://ga.water.usgs.gov/edu/pictures/wcclouds.jpg

10. Precipitation Any water falling to Earth’s surface Examples: Rain Snow Sleet Hail Dew Frost http://farm5.static.flickr.com/4079/4872194918_3a1de0ba90_m.jpg

11. Team Time Draw the process of precipitation.

12. Infiltration Ground water soaking into the soil From the soil: Soaked up by roots Becomes ground water http://ga.water.usgs.gov/edu/pictures/wcinfiltration.jpg

13. Surface Runoff Precipitation runoff over the landscape Occurs when: Water falling on ground > infiltration rate http://ga.water.usgs.gov/edu/pictures/wcrunoff.jpg

14. Groundwater Water located below the ground’s surface Consider this: Digging in sand close to ocean Water that appears is groundwater http://ga.water.usgs.gov/edu/pictures/wcgwstoragebeachlores.jpg

15. Absorption Roots removing water from soil Example: Sponge and water http://farm4.static.flickr.com/3542/3282843423_5ed72e45ac_m.jpg
