Layers of the Earth What’s inside?

A Slice of the Earth the layers……. Inner Core Outer Core Mantle Crust

INNER CORE About 4000 miles below the Earth’s surface is a solid ball of mostly iron and nickel which is the inner core.

OUTER CORE The outer core extends to a depth of around 3000 miles beneath the surface. It is believed to be made up of super-heated liquid molten lava. This lava is believed to be mostly iron, and nickel.

MANTLE The mantle extends to a depth of approximately 1,800 miles, and is made of a thick solid rocky substance that represents about 85% of the total weight and mass of the Earth

CRUST The crust consists of about 10 miles of rock and loose materials. Underneath the continents, the crust is almost three times as thick, as it is under the oceans.
