Convergent plate boundaries is were plates come together. Most destruction that the crust takes place along is convergent boundaries where plates are moving toward each other. Sometimes one plate sinks under another.Plus there are two other different boundaries I did not talk about that I will talk about now. One subduction boundaries is a sub-type boundary. Its called that because it is a boundary between plates. Another sub-type boundary is collision boundaries. Its the boundary that forms when two continents collide and are welded into a single larger continent that is what a collision boundary is.

Areas where plates are being torn apart and new plates getting created. Lots of volcanic activity is resulted and some earthquakes in divergent boundaries. "Rift Valley" is what divergent boundaries are called on land. They are mid-ocean ridges in the ocean. These boundaries are able to occur on the land or under the ocean. Usually found at spreading centers either mid-continental rift zone or mid-ocean ridges.

Transform boundaries are two plates sliding horizontally past one another it is which is the zone between two plates. These large faults and fracture zones who connect two spreading centers (convergent plate boundaries) trench's, or less commonly (divergent plate boundaries) center. Most commonly transform faults are found on the ocean floor.

Plate tectonics is a theory that describes interaction of these plates and the formation movements.
