Asthenosphere: The layer immediately surrounding the lower mantle; composed of molten rock.

Core: Innermost layer of the earth; divided into an inner and outer core.

Crust: The outermost layer that forms the surface of the earth; upper part of the lithosphere.

Geosphere: All of the layers of Earth's interior and crust.

Inner core: Innermost region of the earth; composed of solid iron.

Lithosphere: The cool, rigid shell that includes the crust and uppermost mantle; composed of plates that move around on the underlying, plastic asthenosphere.

Lower mantle: Innermost layer of the two mantle layers; composed of rock and cooler than the core.

Mantle: Middle layer of the earth; composed of an upper and lower mantle.

Outer core: Layer immediately outside the inner core composed of liquid iron sulfur.

Upper mantle: Outermost layer of the two mantle layers; includes the asthenosphere and lower lithosphere; composed of solid rock, most of which flows due to convection currents within the mantle.
