3. Water Cycle- Fill in your diagram
Step 1- Sun heats water.

4. Water Cycle- Fill in your diagram
Step 2- Water evaporates as water vapor into the atmosphere.

5. Water Cycle- Fill in your diagram
Step 3- Water condensates into clouds.

6. Water Cycle- Fill in your diagram
Step 4- Clouds release water as precipitation- rain, snow, hail

7. Water Cycle- Fill in your diagram
Step 5- Water runs along the ground or soaks into the soil

8. What is a watershed?
All the water underground and above ground that flows into the same place (river, lake)
Can be large, or small

9. What is a watershed? 2,110 watersheds in the US
Also called a drainage basin

10. What is surface water?
All surface water drains into a major body of water- lake or river
Eventually most water flows into the ocean

11. What is a runoff? Water enters the watershed through precipitation
Most precipitation falls on land and becomes runoff
Runoff is water that does not soak into the soil but “runs” into lakes, river, etc

12. What is groundwater?
Water that does soak into the soil is called ground water.
As water soaks into the ground it passes through layers of porous rock.

13. What is groundwater?
Rock that is porous allows water to flow through it.
Soil can have different levels of porousness.
This flow of water through the soil is called percolation.

14. What is percolation?
Some soil allows a lot of water to flow through and some does not let hardly any
Water sinks down until it reaches a layer of rock or clay that it cannot pass through

15. What is percolation?
Water that collects on top of that layer is called groundwater.
The layer of rock that is saturated (filled) with water is called an aquifer.

16. What is the water table?
The very top of an aquifer is called the water table.
The water table can be on the surface, close to the surface or hundreds of feet down.

17. What is a watershed divide?
Surface water is divided by watershed divides.
A watershed divide is a high point on the land that divides one watershed from another.
Rivers are divided into tributaries- smaller streams that connect off the larger river.

18. Watershed- Fill in your diagram
Step 1- Precipitation adds water

19. Watershed- Fill in your diagram
Step 2- Water runs down the watershed divide.

20. Watershed- Fill in your diagram
Step 3- Water runs into tributaries.

21. Watershed- Fill in your diagram
Step 4- Water soaks into the ground- called percolation.

22. Watershed- Fill in your diagram
Step 5- Water settles into as groundwater in an aquifer.
