OCEANS FACTS ABOUT THE GREAT BLUE WATERS OF OUR EARTH by Vicky Sivillo
The Earth has 5 oceans……. The Atlantic, Pacific, Arctic, and Indian… In the year 2000, they named a new one called the Southern Ocean, it surrounds the Antarctic region, called the South Pole
DID YOU KNOW… The ocean covers 70% of the Earth and supplies 97% of the world’s water
The ocean serves MANY purposes THE OCEAN… • keeps our weather balanced by absorbing heat from the sun and the always moving ocean distributes the heat around our Earth. • It is home to many forms of life, from the smallest plant called plankton, birds, fish, to the largest mammal, the blue whale. • It provides us with food to eat, but we cannot drink the water, do you know why??
BECAUSE … 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.
DID YOU EVER WONDER WHY… 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.
DID YOU KNOW THAT… 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.
