Where an oceanic and continental plate converge.
|Plate Tectonics Page|
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.
