COMPOSITION OF THE EARTH

Composition of the Earth.

The Earth is made up of a number of parts, some of them are constantly moving!

You can think of the Earth as being made up of a number of layers, sort of like an onion. These layers get more and more dense the closer to the center of the earth you get. See the picture below to see the four main layers of the earth: the crust, mantle, outer core, and inner core.
