1. EQ: Where is Earth’s water located
EQ: Where is Earth’s water located? What percentage of water is available for our use?
LT: I can able to explain the processes by which water moves through the water cycle.
POU: I will create a graph showing the distribution of Earth’s water resources Warm Up
Finishing where is Earth’s water? & Graph

2. Warm-Up: Friday 2/21/14
Where is the majority of the water on Earth located?
Where is the majority of the Fresh Water on Earth located?

3. Water on Earth Notes 11

4. Draw Picture of Demo…

5. Where is Earth’s Water? Demo
If a 1L bottle held all the water on Earth….
☂ Ocean would be in 97% (970 mL)
☂ Freshwater would be the remaining 3% (30mL)
(Freshwater aka “sweet” water – NOT salty)
So we can only use the Freshwater – where is it?
☂ Most is Solid Ice (Glaciers & Icebergs): 76% (22 mL)
☂ Shallow Groundwater (Useable) : 12% (3.6 mL)
☂ Deep Groundwater: 11% (3.3 mL)
☂ Lakes and Rivers: 0.34% (0.1mL)
☂ Water Vapor: 0.03% (0.01mL)
The only usable water is in Lakes and Rivers and Shallow Groundwater (<1% of original 1L amount)

6. Total Water on the EARTH!
How much water do we have?
Total volume of water on the planet:
332,500,000 cubic miles or
332,500,000,000,000,000,000 gallons or
(332.5 million trillion gallons)

7. All Earth's water, liquid fresh water, and water in lakes and rivers
Spheres showing:
All water (sphere over western U.S., 860 miles in diameter)
(2) From #1, this is all the fresh liquid water in the ground, lakes, swamps, and rivers (sphere over Kentucky, miles in diameter),
(3) From #2, this is all the fresh-water from lakes and rivers we use the most(sphere over Georgia, 34.9 miles in diameter).

8. The Basics
The water present on the earth today is the same water that was formed with the planet itself.
The amount of water cannot be increased or decreased.
The unending circulation of the earth’s water is called the Water Cycle.

12. **Fresh Water we CAN’T use because we DON’T have access to it**

13. 76% ICE
Continental Glaciers on Antarctica (South Pole) contain 90% of the world’s Ice
Ice around the North Pole includes:
Sea Ice covering much of the Arctic Ocean
Continental Glaciers covering Greenland

14. 11% Deep Groundwater
Not all the Earth’s Groundwater is available for human use.
Below a certain depth it is not practical (too difficult and expensive) to raise the groundwater to the surface

15. 0.037% Water Vapor
This consists of the water that is in the air and clouds

16. **Fresh Water we CAN use**

17. 12% Shallow Groundwater
About ½ of the U.S. population gets at least some of it’s fresh water from this source
Far more fresh
water is located
underground than in
the rivers and lakes

18. 0.34% Lakes and Rivers These are used for recreation as well as
drinking water

19. Earth’s Water Coloring
Glue Graph paper into your notebook
page 11
You and your table partner read the handout and follow the directions

20. Earth’s Total Water Resources- Salt and Fresh
KEY
Ocean 97%
Fresh Water
Ice, Snow, Glaciers 76%
Groundwater 23%
Lakes, Rivers,
Atmosphere, Other 1%
