EARTH’S WATER

CHAPTER 11 FRESH WATER

11.1 THE WATER CYCLE

Identify how Earth’s water is distributed among

saltwater and freshwater sources.

Describe how Earth’s water moves through the

water cycle.

ENGAGE/EXPLORE

Have a student

describe a rainstorm.

Where does the water

come from that falls as

rain?

How does the water

get into the clouds?

DISCOVER - WHERE DOES THE WATER COME FROM?

Fill a glass with ice

cubes and water, being

careful not to spill any

water. Wait 5 minutes.

Observe the outside of

the glass and the surface

it was sitting on.

INTRODUCTION - NOTES

Why is Earth called

the “water planet”?

From space, this is

the image that

astronauts see.

Oceans cover

nearly 71 percent of

Earth’s surface.

I . WATER ON EARTH - DEMO

Most of Earth’s water is 97% percent salt

water that is found in oceans.

Only 3% is fresh water. • 76% ice masses• .037% atmosphere (water vapor in a gaseous

form. • Less than 1% is fresh water available for human

use. • Some of the Earth’s fresh water is deep

underground.

A. OCEANS

All Earth’s oceans

are connected to

form a single world

ocean.

B. ICE - ARTIC AND ANTARCTICA

Icebergs are

formed from frozen

fresh water.

D. BELOW EARTH’S SURFACE

Groundwater - water that fills the cracks and spaces in underground soil and rock layers .Far more fresh water is located underground than in all Earth’s rivers and lakes.

II. THE WATER CYCLE

Water Cycle - the

continuous process by

which water moves through

the living and nonliving

parts of the environment.

All the water on Earth has

been through the water

cycle.

II. THE WATER CYCLEIn the water cycle, water moves from bodies of

water, land, and living things on Earth’s surface to

the atmosphere and back to Earth’s surface.

The sun is the source of energy that drive the

water cycle.

Prentice Hall video and activity

A. WATER EVAPORATES

Exploring the water cycle p. 363. Evaporation - the process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state. Ocean water that evaporates isn’t salty because the salt remains in the ocean.

PLANTS

Plants take in water by drawing in water form the soil through their roots. Transpiration - water given off through the leaves as water vapor.Plants give off a large amount of water.

C. WATER FALLS AS PRECIPITATION

Precipitation - water that falls to Earth as rain, snow, hail, or sleet. Precipitation occurs when water droplets in a cloud grow larger and larger. They become so heavy that they fall to Earth.

Precipitation is the source of all fresh water on and

below Earth’s surface.

The water cycle renews the usable supply of fresh

water on Earth.

The total amount of water on Earth has remained

fairly constant and balanced.

Water cycle song - “Clementine”

Most water falls in the ocean which may stay there for many years.Some water falls on land & evaporates immediately.Some water runs off into rivers and lakes.Some water trickles down into the ground.

QUESTIONSWhat are the three processes in the water cycle?

Answer: evaporation, condensation, precipitation

Which process begins the cycle?

Answer: a cycle has no beginning and no end. The

water cycle is continuous.

HOW DO PEOPLE USE WATER?

CH. 11.2 ICEBERGS - P. 376

Titanic movie clip

ICEBERGS

Titanic movie clip

Glaciers move over land and

when they hit water they become

an iceberg.

10,000 form every year from

Greenland.

Only about 10 percent of an

iceberg is visible.

90% of an iceberg lies below the

surface.

ICEBERG

The underwater part is a

hazard to ships because it

is often much wider than

the visible part of the

iceberg.

The International Ice

Patrol is now set-up to

track icebergs.
