WHAT DO YOU KNOW ABOUT THEM?
Oceans cover about 70% of the Earth. In the oceans there’s about 97% of all water. Life began in the ocean.
HOW MANY OCEANS ARE THERE?
Read, look at the map and write in the names of the oceans. All oceans are connected. Water and animals can move from one ocean to the other.
The Pacific is the largest. It has more islands than other oceans – about 25,000. There are many volcanoes. There’s often very bad weather. The Pacific lies between Asia in the west and America in the east.
The Atlantic lies between America in the west and Africa and Europe in the east. The Bermuda Triangle lies in the Atlantic. Ships have been wrecked1 and planes havecrashed2 there and we don’t know why.
The Indian Ocean lies between Africa in the west, Australia in the east, and Asia in the north. It is the warmest ocean. The waters are rich in oil.
The Arctic Ocean is small and not very deep. It is very cold. It lies in the northern polar areas. Much of the water is covered with ice.
The Southern Ocean lies around Antarctica. It is the newest named ocean. It was created in 2000. It is the youngest ocean, too. Under the ice the water is very cold (-2°C). The waves in some places are the highest in the world.
