THE WATER CYCLE
Evaporation, condensation,
Precipitation on my mind,
They are part of the
Water cycle, and
It happens all the time.

2. WATER ON EARTH Water is important because:
* Plants and animals need water to live.
* Without water, there could be no rain or snow.
Most water on Earth is salt water found in the oceans.

3. FRESH WATER ONLY A LITTLE OF EARTH’S WATER IS FRESH WATER.
FRESH WATER IS FOUND:
AS ICE IN GLACIERS
RAIN OR SNOW
RIVERS, STREAMS, PONDS, LAKES
GROUNDWATER: FRESH WATER FOUND UNDER EARTH’S SURFACE

4. SALT WATER Largest ocean on Earth – Pacific Ocean
Salt in salt water comes from WEATHERED rocks.
Ocean water has many resources:
Fish, ocean animals, plants used for food
Oil comes from wells under the ocean

5. WHERE FRESH WATER AND SALT WATER MEET
                                                                                                                                                      
ESTUARY: A PLACE WHERE FRESH WATER FROM A RIVER MIXES WITH SALT WATER FROM THE OCEAN

6. THE WATER CYCLE LIQUID – liquid water SOLID – ICE GAS – WATER VAPOR
Form water takes depends upon the amount of HEAT or thermal energy in it.
Three form of water:
LIQUID – liquid water
SOLID – ICE
GAS – WATER VAPOR

7. EVAPORATION Changing of a liquid into a gas
(water) (water vapor)
HEAT must be added to a liquid to make it evaporate.
EVAPORATION CHANGES LIQUID WATER INTO INVISIBLE GAS – WATER VAPOR.

8. CONDENSATION Condensation is the changing of a gas into a liquid.
Taking HEAT away from a gas or cooling it, changes the gas into a liquid.

9. PRECIPITATION
Precipitation is any water that falls to Earth as rain, snow, sleet or hail.

10. THE WATER CYCLE
THE MOVEMENT OF WATER FROM EARTH’S SURFACE INTO THE AIR AND BACK TO THE SURFACE AGAIN.
THIS CYCLE IS POWERED BY HEAT
FROM THE SUN.
