blue from the outer space. So, it is also called the Blue Planet .

We can live because there are air and water on the Earth, and because we
get heat and light from the Sun.

We live on the land, so do many other animals like dog, horse, lion, giraffe

and snake. Many animals live in water, like fish, whale and seahorse. Some
animals can fly, like myna, eagle and butterfly. Some animals can live both

in water and on land, like frog, snake and crocodile.

meeting at a distance. In fact, they can never meet. The line at which they
seem to meet is called horizon .
