• EQ: Where is Earth’s water located? What percentage of water is available for our use?

• LT: I can explain the processes by which water moves through the water cycle.

• POU: I will describe how water is distributed across the Earth. I can identify the percentages of fresh water available for human use.

Welcome! Warm-up 2/20How many gallons of water do you

think we need to grow/make:

1. Bread (1slice)

2. Chicken (1pound)

3. A Cotton Shirt

Water Cycle Vocabulary 101. Condensation – the process of warm air cooling as it rises

and releasing moisture in the form of a liquid

2. Evaporation – the process by which a liquid is changed into a vapor

3. Groundwater – water located below Earth’s surface

4. Hydrosphere – the portion of the Earth that contains water

5. Precipitation – the rain, snow, sleet or hail that falls from clouds onto the Earth’s land and oceans

6. Surface Water – water found on the surface of the Earth

7. Transpiration – water vapor given off by plant photosynthesis

8. Water Cycle – the continuous movement of water from the ocean to the atmosphere to the land and back to the ocean

Water on Earth Notes 11

Where is Earth’s Water? DemoIf 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)

Draw Picture of Demo…

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 riversSpheres showing:(1)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

• Glue Graph paper into your notebook
