1. UNIT 11

2. What is the water cycle? Take a second to study the picture and talk to your table mates before you learn more.

3. Evaporation is … The state of a liquid changing into a vapor (gas). Evaporation is invisible. Evaporation requires energy (like the sun or a burner).

4. Condensation is… When the vapor (gas) cools and turns back (condenses) into liquid. The tiny droplets form CLOUDS.

5. Precipitation is… When the water returns back to the earth as: SNOW FREEZING RAIN HAIL RAIN

6. Collection is… The water that falls back to the ground collects in rivers, lakes, and oceans.

7. Runoff is… Collected water that flows downhill b/c of gravity. Some seeps into the ground as infiltration. Water that infiltrates is called groundwater.

8. Transpiration… Occurs when plants Release water vapor into the atmosphere Is about 10% of our atmosphere’s water.

9. Sublimation… Occurs when solid water directly changes to vapor Occurs when dry air blows over snow or ice Air is very cold then & the pressure is LOW

10. Ice Flow… Much of our ice is in large caps in Antarctica & Greenland Many glaciers are found at high altitudes thus gravity has the ability to pull these down as “rivers of ice”

11. SOLID, LIQUID, or GAS

12. SolidLiquidGas Something that has a defined shape. Gases can fill a container of any size or shape and are invisible. It will take the shape of whatever container it is sitting in.

13. Is it a solid, liquid, or gas? Be able to explain your thought!
