• Asthenosphere
• Mesosphere
• Inner Core
• Outer Core

Earth's three main layers, the crust, mantle and core, are divided based on the composition of each layer.

• Compositional Layers
• Physical Layers

Earth can be divided into five layers: the lithosphere, asthenosphere, the mesosphere, the outer core and the inner core based on how the layer behaves, like a liquid or solid, or how it transmits waves.

• Compositional Layers
• Physical Layers

The thin and solid outermost (compositional) layer of Earth above the mantle mainly composed of oxygen, silicon and oxygen.

• Crust
• Mantle
• Core

The (compositional) layer of hot, slow flowing, solid rock between Earth's crust and core.

• Crust
• Mantle
• Core

The (compositional) layer of the Earth that extends below the mantle to the center of the Earth which is mostly made of iron and some nickel.
