2. 1. Ocean plates move apart from each other (diverge)

3. 2. Mountains form because of the uplift of material.

4. 3. Faults, like the San Andreas, form. Many earthquakes occur along these faults.

5. 4. Subsidence occurs. The Great African Rift Valley is an example.

6. 5. Plates moving together (converging) forming a ring of volcanoes around the edges of the continents and encircling the Pacific Ocean.

7. Two plates collide and one is pulled underneath the other at a subduction. The plate that is pulled under melts, creating magma that rises.
