Final Exam #6






The Water Cycle
Shelby Cook
4th Hour

A) The water Cycle happens in all places and things. There are 8 different processes in the Water Cycle. Evaporation Is the process by which water changes from a liquid into a gas or vapor. It’s the primary way that liquid can get back into the water cycle. Transpiration Begins in a plants roots. The water moves from the roots to the leaves where it evaporates into the atmosphere. Condensation is when vapor in the air is turned into a liquid. The opposite affect of evaporation and transpiration. Precipitation is and form of rain, whether it be sleet, hail, snow, or freezing rain. It delivers atmospheric water to the earth. A portion of water that falls to the earth, including snow, soaks into the rocks and soil which is known as Infiltration. A portion of the precipitation that hits earth runs off into river, streams, ect. This is called surface runoff. It is very important because much water that was evaporated returns to the oceans. Groundwater is simply water that comes from the ground. Absorption is important especially for plants to regain the water they need to live.

B) Only 30- 40 percent of the snow and rain we see hit the ground actually goes back into the rivers, lakes, and streams. The rest goes into plants and Ground water which moves to nourish forests and replenish aquifers. Water Cycling cools the planet and cleans the air.








C) Streams Run into rivers that eventually run into the oceans. The same time the water leaves the river more is being run into the river. When winter snow melts the rivers are more likely to flood. The groundwater has taken on so much the river will take on more. Floods can make soil very fertile therefore the food is greater in amount and richer.
