Scientists and geologists have a pretty good understanding of how the plates move and how this is related to earthquake activity. There are four different types of plate boundaries. First we have Divergent boundaries, where new crust is generated as the plates pull away from each other. Second we have Convergent boundaries and this is where the crust is destroyed as one plate is forced under another. Third we have the transform boundaries and this is where the crust is not created or destroyed as the plates slide horizontally past the other. Last we have Plate boundary zones where broad belts in which boundaries are not well defined and plate interactions are not clearly understood. The best known divergent boundaries is the mid-Atlantic Ridge, it is a submerged mountain range, which extends from the Arctic Ocean down South of Africa. This mountain range has been spreading apart for millions of years, which allows new magma to surface thus increasing the size of the mountains 2.5 centimeters each year. The two plates involved here are the American and the Eurasian plates and they are separating Iceland. The convergent boundaries are where the crust is being destroyed at about the same rate as it is
