Beneath Our Feet: The Layers of the Earth

This layer of the earth extends approximately 1,800 miles deep into the Earth. It makes up 85% of the total weight of the Earth's mass and is also made of layers of hard rock and super-heated molten rock that flows like tar.

This is about 3,000 miles beneath the Earth's surface. It consists of super-heated liquid molten lava. This layer creates the Earth's magnetic field, since it is mostly made up of iron and nickle (molten metal.)

• outer core

• inner core

• atmosphere

• crust

This gives the earth its shape and is arranged in a particular way.

• surface

• structure

• rocks

This is the final layer and is a solid ball of iron and other minerals. The temperature is extremly hot (over 9,000 degrees Farenheit.) This layer is often compared to the sun.

• mantle

The molten rock inside the Earth's mantle is called

• liquid metal

• minerals

When the molten rock inside the Earth's mantle erupts through a volcano, it is called
