  6. Continental-Continental Collisions • --When two tectonic plates with continental crust collide, they buckle and thicken, which pushes the continental crust upward. • Continental-Oceanic Collisions • --When a plate with oceanic crust collides with a plate with continental crust, the denser oceanic crust sinks into the asthenosphere. This convergent boundary has a special name: the subduction zone. Old ocean crust gets pushed into the asthenosphere, where it is remelted and recycled. • Oceanic-Oceanic Collisions • --When two tectonic plates with oceanic lithosphere collide, one of the plates with oceanic lithosphere is subducted, or sinks, under the other plate. • Moving Apart • --At a divergent boundary, two tectonic plates separate from each other. As they move apart, magma rises to fill the gap. At a mid-ocean ridge, the rising magma cools to form new sea floor. • Sliding Past • --At a transform boundary, two tectonic plates slide past one another. Because tectonic plates have irregular edges, they grind and jerk as they slide, which produces earthquakes.

  7. Normal Faults often form when rocks are pulled apart because of tension. • Reverse Faults often form when rocks are pushed together by compression. • Strike-Slip Faults are often formed when rocks are moved horizontally by opposing forces.
