EARTH'S OCEANS
Oceans cover about 70% of the Earth's surface. The oceans contain roughly 97% of the
Earth's water supply. The oceans of Earth are unique in our Solar System. No other planet in
our Solar System has liquid water (although recent finds on Mars indicate that Mars may have
had some liquid water in the recent past). Life on Earth originated in the seas, and the oceans
continue to be home to an incredibly diverse web of life.
The oceans of Earth serve many functions, especially affecting the weather and temperature.
They moderate the Earth's temperature by absorbing incoming solar radiation (stored as heat
energy). The always-moving ocean currents distribute this heat energy around the globe. This
heats the land and air during winter and cools it during summer.
THE OCEANS
The Earth's oceans are all connected to one another. Until the year 2000, there were four
recognized oceans: the Pacific, Atlantic, Indian, and Arctic. In the Spring of 2000, the
International Hydrographic Organization delimited a new ocean, the Southern Ocean (it
surrounds Antarctica and extends to 60 degrees latitude).
There are also many seas (smaller branches of an ocean); seas are often partly enclosed by land.
The largest seas are the South China Sea, the Caribbean Sea, and the Mediterranean Sea.
Find the deepest points in an atlas. Mark the deepest point in each ocean with an X.

Label the Earth's Oceans
Read the definitions, then label the map below.
Definitions
Arctic Ocean - an ocean around the North Pole, bordering northern Europe, Asia and North
America. It is the smallest ocean.
Atlantic Ocean - an ocean bordering western Europe, western Africa, Antarctica, and eastern
North and South America.
Indian Ocean - an ocean bordering eastern Africa, southern Asia, western Australia, and
Antarctica.
Pacific Ocean - an ocean bordering eastern Asia, northeastern Australia, Antarctica, and
western North and South America. It is the biggest ocean.
Southern Ocean - the ocean bordering Antarctica and extending from 60 degrees latitude.
This fifth ocean was recognized by the International Hydrographic Organization in the spring
of 2000.

Equator and Poles
At the top of the earth is the North Pole. It is as far North as you can go.
At the bottom of the earth is the South Pole. It is as far South as you can go.
Around the middle of the earth is an imaginary line called The Equator. The
Equator is half way between the North Pole and the South Pole.
1. Draw a red line along the equator.
2. Draw a red dot for the North Pole.
3. Draw a red dot for the South Pole.
4. Which continents does the Equator pass through?
5. Which oceans does the Equator pass through?
6. Which ocean contains the North Pole?
7. Which continent contains the South Pole?

Hemispheres
Northern Hemisphere and Southern Hemisphere
A hemisphere is half of a sphere or ball. The Equator divides the earth into two
hemispheres. They are the Northern Hemisphere and the Southern Hemisphere.
The annual seasons are opposite in the Northern and Southern Hemispheres.
When it is summer in one hemisphere it is winter in the other. When it is spring in
one hemisphere, it is autumn in the other.
The Northern Hemisphere.
The North Pole is in the
center of the Northern
Hemisphere.
North America, Europe and
Asia are in the Northern
Hemisphere. The Northern
Hemisphere also includes
parts of Africa and South
America.
The Southern Hemisphere.
The South Pole is in the center
of the Southern Hemisphere.
Antartica and Australia are in
the Southern Hemisphere. The
Southern Hemisphere also
includes most of South America
and Africa.

Hemispheres
Eastern Hemisphere and Western Hemisphere
The Eastern Hemisphere stretches from the North pole to the South pole
between the International Date Line and the Greenwich Meridian.
Day and night are different in the Eastern and Western Hemisphere. When it is
day in a Hemisphere, that Hemisphere is facing the sun. When it is night, that
hemisphere is facing away from the sun.
The Eastern Hemisphere.
The Eastern Hemisphere
includes the continents of Asia,
and Australia. The Eastern
Hemisphere also includes most
of Africa and most of Europe.
The Western Hemisphere.
The Western Hemisphere includes
the continents of North America and
South America. It also includes part
of Africa.
