1. Water, Water Everywhere!
Water in Earth’s Processes
Unit
S6E3

2. How is the amount of water on Earth divided up?
3% = Freshwater
97% = Saltwater

3. Is most of the water on Earth freshwater or saltwater?

4. Where can the freshwater be found?
¾ Freshwater is Frozen Solid
in ice caps and glaciers
¼ Freshwater is Liquid underground
A tiny fraction is in lakes & rivers
A smaller fraction is water vapor in the atmosphere

5. What is the Water Cycle?
Definition: The continuous movement of water from Earth’s surface into the atmosphere and then back again!
The water cycle is powered by the Sun.

6. Condensation
Precipitation
Evaporation
Trees
Accumulation

7. Main Parts of the Water Cycle:
Evaporation
Condensation
Precipitation
Accumulation

8. What is Evaporation?
When water changes from liquid to water vapor (liquid to gas)
Evaporation comes from:
plants
lakes
oceans

9. Evaporation from plants????
This is called TRANSPIRATION

10. What happens after water evaporates?
Condensation!
As air and water vapor rise, they cool to form clouds
(gas to liquid)

11. What happens when the droplets get too large to stay in the clouds?
They fall as Precipitation –
water that falls from clouds as
Rain
Snow
Sleet
Hail

12. What happens to water that falls to the ground?
Accumulation- collection of water
Runoff – water flows across the land into streams, rivers, or oceans
Groundwater – water soaks into the ground

13. Examples of surface water:
Rivers
Ponds
Lakes
Wetlands – swamps, bogs, marshes

15. How does water get UNDERGROUND?
It trickles down between
particles of soil & through
cracks in rocks

16. How water gets into rock…

17. An Aquifer is an underground layer of rock or sediment that holds water.

18. How can we get to the water so we can use it everyday?
Springs can form & water bubbles out naturally
Wells provide access to Aquifers that have drinking water
Wells can be mechanically or hand pumped
In Artesian Wells, water rises because of pressure in an Aquifer

19. Why is it important to conserve water?
How is water used?
In your home
Industry & Transportation
Agriculture
Recreation
