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?

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.
