The Earth

The Earth is made of water and land.

70% of the surface is covered with water and 30% by land.

Water can be liquid as in: rivers, lakes, seas and oceans

 or solid as in the ice found in the North and South Poles.

The land can be dry as in desserts or wet as in rainforests.

Layers of the Earth

The Earth is like an onion, made of layers. The four main layers are:  Crust, Mantle, Outer Core and Inner Core. It is also made of three elements: liquid, solid and gas that make possible the existence of life on Earth.
