 convergent
Convergent plates are the plates that grind against each other. These plates that are sometimes called strike slip faults caused what we called the San Andreas. These is what called north specific ocean to have trenches in the pacific plate. There is also the term subduction which means that when plates overlap and then form mountain. Japan is a mountain formed from an underwater trench. Divergent Divergent boundaries accure in the earths oceans. Magma erupts through the crack made by the divergent. The great rift vally in africa is one example of the earths divergent boundaries. Magma causes the plates to move seperately. The magma causes the plates to move in in two or more.

Transform Transform is when two plates slide past each other. They grind against each other which causes serious earthquakes. The san andreas fault is an example of a transform. Sometimes called a strike slip when stopped can cause serious earthquakes. Another example is the san franscico. "plate tectonics." //national geographic//. Web. 12 Nov. 2009. .
