Earth's outer core

The Earth has a special part deep inside it called the outer core. It is a thick layer of liquid that is very far below our feet! The outer core is made mostly of two metals: iron and nickel.

The outer core is right above the solid inner core and below a thick part called the mantle. It starts about 2,889 kilometers (1,795 miles) under the ground and ends about 5,150 kilometers (3,200 miles) under the ground.

This outer core is very important because it helps create Earth's magnetic field. This magnetic field protects us from harmful space rays and helps make our planet a nice place to live. The outer core is very hot, and its movement helps keep our magnetic field strong.
