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

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?

Water on Earth Notes 11

Draw Picture of Demo…

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)

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)

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, 169.5 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).

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.

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

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

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

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

**Fresh Water we CAN use**

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

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