The compositional layer of hot, viscous, almost solid, magma between Earth's crust and core.

• Crust

• Mantle

• Outer Core

• Inner Core

The liquid layer of the Earth's core. Very dense. Made of heavy metals.

• Outer Core

• Inner Core

An extremely dense sphere of solid iron and nickel at the center of Earth.

• Outer Core

• Inner Core

The rigid outer part of the earth, consisting of the crust and upper mantle. Earth's outermost mechanical layer.

• Lithosphere

• Asthenosphere

• Mesosphere

• Core

The mechanical layer beneath the asthenosphere. It's the strong, lower part of the mantle between the asthenosphere and the outer core.
