Plate Tectonics Study Review with Solutions
earthquake - -sudden, violent movements of
Earth's crust
rift valley - -A low lying area created by a
divergent plate boundary.
dense - -Closely packed together. When plates
collide the plate that is more __________ will
subduct (go beneath the other). mid-ocean ridge - -An underwater moutain
chain where new ocean floor is formed
mountains - -Formed by two continental plates
colliding and forcing each other upwards. Ring of fire - -A circle of volcanoes surrounding
the Pacific Ocean.
subduction - -A collision between an oceanic
plate and a continental plate pushing the oceanic tectonic plates - -Sections of the Earth's crust
plate under the continental plate where it can remelt. that move due to convection currents.
fault - -a crack in the earth's crust where land Alfred Wegener - -The scientist that is credited
is neither created nor destroyed, only moved. with first proposing the Theory of Continental Drift.
convergent - -Boundaries where plates move asthenosphere - -the layer of the earth's

flows and convection is thought to occur.
divergent - -Boundaries where plates move
away from each other, forming either mid-ocean Continental Drift - -The theory that the
