Divergent Plate Boundary
The plates move away from each other. They experience tension. Oceanic divergent plate boundaries create mid-ocean ridges and volcanos. Continental divergent plate boundaries also cause volcanos, as well as continental rifts. Examples of divergent plate boundaries are the Mid-Atlantic Ridge, East Pacific Rise, and the East-African Rift. In December 2005, there was a 6.8 earthquake in Africa under Lake Tanganyika. There were six casualties.

Convergent Plate Boundary
The plates move towards each other. They experience compression. Continental-continental plate boundaries cause mountains. Continental-oceanic plate boundaries create volcanos. Krakatoa is an example of a volcano created by convergent plates. The volcano erupted in 1883 and it is estimated that it killed more the 36,000 people.

Transform Plate Boundary
Transform plate boundaries slide horizontally. These plate boundaries create fault lines. The stress they experience is shear stress. An example of a popular fault line is the San Andreas fault. In 1906 the San Andreas fault caused an earthquake that was estimated to be 7.8. It killed more than 3,000 people and destroyed more than 28,000 buildings.
