Continental Crust - the thick parts of the Earth's crust, not located under the ocean.
Lithosphere - the crust plus the rigid, upper mantle.
Lower Mantle (semi-rigid) - the deepest parts of the mantle, just above the core.
Mohorovicic discontinuity - separates the crust and the upper mantle.
Ocean - large bodies of water sitting atop oceanic crust.
Oceanic Crust - thin parts of the Earth's crust located under the oceans.
Upper Mantle (rigid) - the uppermost part of the mantle, part of the Lithosphere.
Upper Mantle (flowing) = Asthenosphere - the lower part of the upper mantle that exhibits plastic (flowing) properties. It is located below the lithosphere (the crust and upper mantle).
