Crust:Crust: A very thin, solid outer layer. A very thin, solid outer layer. The oceanic crust is about 5 km thick. The oceanic crust is about 5 km thick. The continental crust is 30–40 km The continental crust is 30–40 km thick.thick.

Moho:Moho: The boundary between the The boundary between the crust and the mantle (named for the crust and the mantle (named for the Mohorovic discontinuity).Mohorovic discontinuity).

Mantle:Mantle: The layer beneath the crust. The layer beneath the crust. The mantle is about 2885 km thick, The mantle is about 2885 km thick, and consists of two layers.and consists of two layers.

Upper mantle:Upper mantle: Includes a solid layer Includes a solid layer fused to the crust, it is about 70 km fused to the crust, it is about 70 km thick. This layer combined with the thick. This layer combined with the crust is called the crust is called the lithospherelithosphere. .

Beneath this is the Beneath this is the asthenosphereasthenosphere, , which is a flowing (plastic-like) partly which is a flowing (plastic-like) partly molten layer. The asthenosphere is molten layer. The asthenosphere is thought to be the layer upon which thought to be the layer upon which tectonic plates ride. The tectonic plates ride. The asthenosphere exists between about asthenosphere exists between about 100 and 250 km deep.100 and 250 km deep.
