Watch and talk
What do you know about the continents on the earth? Let’s watch a video .
The earth
The earth is a special planet. It is our home now, and it will be our home in the future.
Only about one third of our planet is land. There are seven continents: Asia, Africa, Oceania, Antarctica, Europe, North America, and South America. Some land is rich with green forests, fresh water, and good soil. But some places are difficult for humans to live because of the snow and ice, the deserts, or the high mountains.

But people can’t live everywhere on the earth. We can’t live in water. Oceans cover two thirds of the earth’s surface. The earth has only one big ocean, but we use these names for its different parts: the Pacific Ocean, the Indian Ocean, the Atlantic Ocean, and the Arctic Ocean.
The earth is our only home. We must treat it well for our children and for our children's children, too!
