Dynamic Earth

Convergent Boundaries Convergent boundaries occur when two plates collide and hit one another. Convergent boundaries cause mountains, about 55 million years ago india and asia causing a convergent plate to combine crashed slowely causing rise to the highest mountain in the himalay's Mt. Everest which is the highest mountain system on earth. When plates in the ocean go under land masses which are called subduction trenches will form. For example the Mariana Trench was formed in the North Pacific Ocean.

Divergent Boundaries Divergent Boundaries form when plates move apart. In the deep oceans magma rising from the Earth's mantle to the surface and pushes away two or more Divergent Plates. If and when a divergent Boundary is formed in the ocean a crevice will form. The crevice will form volcanoes and mountains underwater. An Example of the divergent boundaries are the Great Rift Valley in Africa. Transform Boundaries Transform Boundaries form when the two plates grind past each other and move sideways in addition to one another which is called strike slip faults. The halting motion of the Transform Boundaries will often trigger or form large earthquakes. An example of a Transform Boundaries is The San Andreas fault. is an example of a Transform boundary.
