Our planet
Our planet Our home is caIled planet Earth. From far away in space, it look like a huge blue ball. This is because seas and 4 cover nearly three quarters of its surface. What land can be seen appears green and broun. But often much of the earth's surface is the hidden by wspy white swirls. These are clouds. Beneath them lies the earth we know, with the mountains, planets, valleys, rivers and lakes.
