Asthenosphere = Upper Mantle (flowing) - the lower part of the upper mantle that exhibits plastic (flowing) properties. It is located below the lithosphere (the crust and upper mantle). Continental Crust - thick parts of the Earth's crust, not located under the oceans. Lithosphere - the crust plus the rigid, upper mantle. Lower Mantle (semi-rigid) - the deepest parts of the mantle, just above the core. Magma - molten rock withing the Earth's mantle. In seafloor spreading, magma moves from the asthenosphere to the crust. Ocean - large bodies of water sitting atop oceanic crust. Oceanic Crust - thin parts of the Earth's crust located under the oceans. Subduction Zone - the area in which one part of the Earth's crust (a plate) is pushed underneath another plate as the two plates collide. Upper Mantle (rigid) - the uppermost part of the mantle, part of the lithosphere. Volcanos - a place on the Earth's surface where molten rock, gases and pyroclastic debris erupt through the earth's crust. |
