 * __Convergent Plate Boundary__

Where plates serving land masses collide the crust crumples and buckles into mountain ranges. India and Asia crashed about 55 million years ago, slowly giving rise to the Himalaya mountains, the highest system on earth. These types of collisions can also lead to under water volcanoes that eventually build up into island arcs like Japan.

Another example of a convergent boundaries are the volcanoes of the Washington-Oregon coastline of the United States.



__**Divergent Boundaries**__

At divergent boundaries in the oceans, magma from deep in the earth's mantle rises toward the surface and pushes apart two or more plates. The process renews the ocean floor and widens the giant basins.A single mid-ocean ridge system connect the world's longest mountain range in the world.If the plates there continue to diverge, millions of years from now eastern Africa will break away from the main continent. A mid-ocean ridge world then mark the boundary between the plates.

**Transform Boundaries** Where two plates grind past each other along what are called strike slip faults. These boundaries don't produce spectacular feaurtes like mountains or oceans but the large earth quakes.


 * The San Andreas Fault in california is an example of a transfrom boundary between the Pacific plate and the North American plate.
