**A divergent boundary is a boundary between two lithospheric plates that are moving apart. Mountains and volcanoes rise along the seem. The process renews the ocean floor and widens the giant basins. A single mid-ocean ridge system connects the worlds oceans making the ridge of the longest mountain in the world. The Great Rift Valley in Africa who's plates are being tugged apart is an example of a divergent boundary. If these plates continue to diverge, millions of years from now Eastern Africa will split from the continent to form a land mass. A transform boundary is where two plates grind past each other along strike-slip faults. Strike-slip faults is a fault where the rocks on the opposite sides of the fault plane move horizontally. These boundaries do not produce features like mountains or oceans. An example of a Transform Boundary would be the the earth quake in San Francisco in 1906 caused by the halting motions of the plates grinding past each other. ****__Convergent Boundary__** A convergent boundary is where plates serving land-masses collide, crust crumbles and buckles into mountain ranges. As this process continues the mountains get higher. An example of a convergent boundary would be India and Asia crashing into each other about 55 million years ago to form the Himalayas, the highest mountains on earth. 11/12 - http://news.nationalgeographic.com/news/2007/08/070816-fast-quakes.htm 11/13 - http://geology.com/plate-tectonics.shtml 11/16 - http://science.nationalgeographic.com/science/earth/the-dynamic-earth/plate-tectonics-article.htm 11/16 - http://sciencedaily.com/release/2005/08/05082095854.htm 11/16 - http://whatonearth.olehielsen.dk/plates/scotia.asp **
