Destructive Plate Margin- Land is destroyed (i.e. One oceanic plate and one continental plate sliding into each other to form an oceanic trench)
Constructive Plate Margin- Land is made (i.e. two oceanic crusts being pulled apart by convection currents in the mantle)
Asthenosphere- The upper mantle (flowing). The lower p[art of the upper mantle that exhibits plastic (flowing) properties. It is located below the lithosphere. The crusts 'float' on top of it.
Continental Crust- thich parts of the Earths crust, not located under oceans. Has an acidic pH. MAinly made of the igneous rock Granite.
Lithosphere- the crust plus the rigid, upper mantle.
Lower Mantle (semi-rigid)- the…
