** __Transform Boundary__ **

 Transform boundary is when to plates grind each other a long what are called strike slip faults. Theses boundaries don't produce spectacular features like mountains and oceans. A strike slip is a simple offset however, a transform fault is formed between two different plates, each moving away from the spreading center of a divergent plant boundary. The halting motion often triggers large earthquakes, such as the 1906 one that devastated San Francisco. The earthquakes are usually shallow because they occur within and between plates that are not involved in subduction.


 * The Jana de faca plate and North America form the San Andreas fault in California.
 * ** The same plates (North American Plate and the Juan de Fuca Plate) as the San Andreas Fault triggered this event. Alaska is having many earthquakes because the Juan de Fuca Plate is rubbing or grinding against the North American Plate. **

 Convergent plates move into one another and the plates are serving landmass collid the crust crumpless, buckles into mountain ranges. These convergent boundaries also occur where a plate of ocean dives, in a process called subduction, under a landmass. As the overlying plate lifts up, it also forms mountain ranges. In addition, the diving plate melts and is often spewed out in volcanic eruptions such as those that formed some of the mountains in the Andes of South America witch form Nasco plate and the caribbean plate. India and Asia crashed about 55 million years ago, slowly giving rise to the Himalaya, the highest mountain system on Earth. At ocean-ocean convergences, one plate usually dives beneath the other, forming deep trenches like the Mariana Trench in the North Pacific Ocean, the deepest point on Earth. These types of collisions can also lead to underwater volcanoes that eventually build up into island arcs like Japan.

 * The Cascades are part of the Pacific Ring of Fire, the ring of volcanoes and associated mountains around the Pacific Ocean. All of the known historic eruptions in the contiguous United States have been from Cascade volcanoesNasca plate and the South America converged to form the Andes Mountains in the western part of South America
 * The Philippine Sea Plate meets the Okhotsk Plate at the Nankai Trough. The Philippine Sea Plate, the Amurian Plate, and the Okhotsk Plate create Mount Fuji in Japan.


 ==Divergent boundies in the oceans, magma from deep in the Earth's mantle vises toward the surface and pushes apart two or more plates. Mountains and volcanos rise along the seam. Renews the oceans floor and wiches the giant basics. Magma rises and pushes plates apart. On land, giant troughs such as the Great Rift Valley in Africa form where plates are tugged apart. If the plates there continue to diverge, millions of years from now eastern Africa will split from the continent to form a new landmass. A mid-ocean ridge would then mark the boundary between the plates.== A narrow sea formed where the African and Arabian Plates are diverging       >
 * The easterly side of the North American Plate is a divergent boundary with the Eurasian Plate to the north and the African Plate to the south forming the northern part of the Mid-Atlantic Ridge.
