FACTS ABOUT THE
GREAT BLUE WATERS OF OUR EARTH
by Vicky Sivillo
In the year 2000, they named a new one
called the Southern Ocean,
it surrounds the Antarctic region,
The ocean covers 70% of the Earth and supplies 97% of the world’s water
the always moving ocean distributes the heat around our Earth.
THE OCEAN IS VERY SALTY.
All water flows through rivers and streams before being deposited into an ocean. On its way, it picks up the small amounts of salt from the minerals found in the rocks and soil. Once in the ocean, the water evaporates, but the salt can not, so over time the oceans get saltier and saltier.
THE OCEAN WAS BLUE?
Scientists believe the ocean appears blue because it reflects the blue in the sky. On a grey, cloudy day the water of the ocean will appear grey also.
Wind causes waves on the surface of water?
The wind picks up the water and the gravity pulls it back down again.
The stronger the wind, the bigger the waves become in the ocean.
