CONVERGENT BOUNDARIES DIVERGENT BOUNDARIES TRANSFORM BOUNDARIES
 * Where plate serving landmasses collide the crust crumples and buckles into mountain ranges.
 * As the mash up continues, the mountains get higher.
 * The convergent boundaries also occur where a plate of ocean dives.
 * Subduction is when the over lieing plates lift up, it also forms mountain ranges.
 * In addition the diving plates melt and it is often spewed out in the volcanic eruptions such as those that formed some of the mountains.
 * At ocean-ocean convergences, one plate usually dives beneath the other, forming deep trenches (mariana trench-deepest point).
 * Those types can lead to underwater volcano's.
 * Nazca plate, named after the nazca region of southern peru, is an oceanic tectonic plate in the eastern pacific ocean off the west coast of south america. It has convergent boundaries subduction zones.
 * Divergent boundaries have magma from deep inside the Earth's mantle rise towards the surface and pushes apart two or more plates.
 * Mountains and volcano's rise along the seam.
 * The process renews the ocean floor and widens giant basins.
 * In a single mid ocean ridge system connects the worlds ocean, making it the longest in the world.
 * African plates is about 1/2 of the land mass with divergent plate boundary on the west edge running through the red sea.
 * An easy way to define divergent boundaries is that the plate push apart, as the picture shows.


 * The san Andreas Fault in Calfornia is an example of transform boundaries.
 * It is when plates grind past each other.
 * They call it strike-slip faults.
 * Transform boundaries don't produce mountains or oceans.
 * Transform boundaries often trigger earthquakes.
 * There was a earthquake in 1906 in san francisco.
