Inside the Earth

The earth has three main parts. The crust the Mantle and the Core

Crust
The crust is the part of the earth we live on .

We can only see the upper part of the crust,

the lower part of the crust is solid rock . 

Mantle
The Mantle is the biggest part of the earth.

The upper mantle is sort of liquid-solid mixture

like hot clay. This lets the plates move and

make earthquakes. The lower mantle is a hot

solid mixture of Iron , Oxygen and other metals

and rocks. Both layers have these things in them.


Core
The core is the center of the earth . The outer

core is hot liquid molten metals . The inner core

is solid from all the pressure of the other layers.

It is made up of iron and metals.


Before the 1900's - 2000's there were many myths
of what was in the earth.
