This layer of the Earth is made up of large amounts of silicon and aluminum.

This is the thickest layer of the Earth making up 70% of the Earth’s mass.

This type of heat transfer sees magma rise to the top of the mantle, cool, then sink, reheat, and rise again causing changes in Earth's surface.

This layer is solid, but capable of flow like hot asphalt or fudge.

This layer is located about 1,800 miles beneath the crust and is about 1,400 miles thick.
