Volcanoes (not needed) Flashcards
Asthenosphere
The upper layer of the mantle prone to melting
Benioff zone
The zone of subducting plate prono to earthquakes
Continental crust
Layer of the earths surface supporting continents
Convection currents
Rising heat and rock in the mantle
Convergence
The coming together of 2 plates
Divergence
The moving apart of 2 plates
Lithosphere
Layer of the upper mantle that are made up of both mantle and crust
Mantle
The largest section of the Earth structure, found between the core and crust
Mantle Wedge
The area of the mantle above the subducting plate and below the lighter plate
Oceanic Crust
Layer of the Earth’s surface supporting ocean
Ridge Push
The process of plate movement caused by the creation of new rock at a divergent boundary
Slab Pull
The main reason for plate movement caused by the subducting plate and gravity
Subduction
The process by which the denser plate sinks beneath the lighter plate
Volatiles
The release of gases and water from the ocean crust into the mantle wedge
