__**Dynamic Earth**__ __Convergent Boundary__ This type of boundary occurs when two plates collide with each other. The land above the plates can either push together and rise creating a mountain or one can give away and go underneath the other. Over 55,000,000 years ago the Indian Plate and the Asian Plate collided and started rising at a boundary which eventually created the Himalayas. Most ocean convergences result in one going underneath the other, such as the Mariana Trench, the deepest place on earth. Underwater volcanoes can form at these type of boundary which slowly create land that rises to the surface. angle

__Divergent Boundary__ This boundary occurs when magma rises and pushes two plates apart. Mountains and volcanoes can form along the seem. In the ocean it renews ocean floor and widens the bases. The Great Rift Valley is a divergent boundary formed by the African plate moving away from another plate. Eventually, this will split Africa apart.

__Transform Boundary__ Transform boundaries are two plates moving past each other. This does not cause any large land masses, but can create massive earthquakes. The San Andreas Fault had created this type of earthquake which devastated San Francisco in 1906.
