2. Water Cycle

3. Storage in Ice and Snow • Water is stored in ice and snow, with a small percentage of it being frozen. • Sometimes days, sometimes thousands of years.

4. Precipitation • When cloud particles become too heavy to remain suspended in the air, they fall to the earth as precipitation.

5. Snowmelt Runoff • Snowmelt runoff is a major component in the water cycle.

6. Infiltration • Infiltration is when the water enters into the subsurface of soil and rocks

7. Ground-Water Discharge • As part of the water cycle, ground water is a major contributor to flow in many streams and rivers and has a strong influence on river and wetland habitats for plants and animals.

8. Ground-Water Storage • Most of the water in the ground comes from precipitation that infiltrates downward from the land surface • Large amounts of water are stored in the ground.

9. Evaporation • Evaporation is the process by which water is converted from its liquid form to its vapor form • This is the primary pathway that water moves from the liquid state back into the water cycle.

10. Water Storage in Oceans • The water in the oceans is saltwater, it contains significant amounts of dissolved salts • 96.5% of the worlds water comes from the ocean

11. Condensation • Condensation is the change of water from its gaseous form (water vapor) into liquid water. • This is crucial because it is responsible for the formation of clouds.

12. Water Storage in the Atmosphere • There is always water in the atmosphere. Clouds are, of course, the most visible manifestation of atmospheric water, but even clear air contains water- in particles that are too small to be seen.

13. Evapotranspiration • Evapotranspiration is the water lost to the atmosphere from the ground surface. • The transpiration part is talking about evaporation of water from plant leaves.

14. Sublimation • Sublimation is when a solid changes directly into a gas • It is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water.

15. Water in Atmosphere • Oceans, seas, and other bodies of water contain about 90% of the moisture in the atmosphere. • Other 10%=plants, transpiration. • 3,100 cubic miles of water.

16. Water in Hydrosphere • Includes all water on earth. • 1.35 million cubic kilometers of water on earth. • Not a single drop of water can be found anywhere else in the solar system.

17. Water in Lithosphere • The solid part of earth. • Is composed of minerals and contains the groundwater.

18. Water in Biosphere • Is all living organisms. • Covers the top 200 meters of oceans and seas.
