UNIT 11
What is the water cycle? Take a second to study the picture and talk to your table mates before you learn more.
Evaporation is … The state of a liquid changing into a vapor (gas). Evaporation is invisible. Evaporation requires energy (like the sun or a burner).
Condensation is… When the vapor (gas) cools and turns back (condenses) into liquid. The tiny droplets form CLOUDS.
Precipitation is… When the water returns back to the earth as: SNOW FREEZING RAIN HAIL RAIN
Collection is… The water that falls back to the ground collects in rivers, lakes, and oceans.
Runoff is… Collected water that flows downhill b/c of gravity. Some seeps into the ground as infiltration. Water that infiltrates is called groundwater.
Transpiration… Occurs when plants Release water vapor into the atmosphere Is about 10% of our atmosphere’s water.
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
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”
SOLID, LIQUID, or GAS
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.
Is it a solid, liquid, or gas? Be able to explain your thought!
