Convergent Boundary

Convergent boundarys are plates serving as landmasses collide and the crust buckles into mountain ranges and volcanos. Suduction is overlaying plate lifts up forming volcanos and mountain ranges. In addition, the diving plate melts and is often spewed out in volcanic eruptions. Trenches happen when a plate dives beneath another to form a trench, Trenches like the Mariana Trench in the North Pacific Ocean, the deepest point on Earth.Collisions can also lead to underwater volcanoes that eventually build up over time. India and Asia crashed about 55 million years ago, slowly giving rise to the Himalaya, the highest mountain system on Earth.The Himilays are still growing because of the plates are still applying force to each other. and growing about a Quarter inch every year.

Divergent Boundary

Divergent boundries in the oceans, magma from deep in the Earth's mantle rises toward the surface and pushes apart two or more plates. Mountains and volcanoes rise along the seam.A single mid-ocean ridge system connects the world's oceans, making the ridge the longest mountain range in the world.On land, giant troughs such as the Great Rift Valley in Africa form where plates are tugged apart.The process renews the ocean floor and widens the giant basins.If the plates there continue to diverge, millions of years from now eastern Africa will split from the continent to form a new landmass.

Transform boundry

The desription is when two plates grind past each other along what are called strike-slip faults.The San Andreas Fault in California is an example of a transform boundry. These boundaries don't produce spectacular features like mountains or oceans, but the halting motion often trigures large earthquackes, such as the 1906 one that devestated san francisco.Some 80 percent of all the planet's earthquakes occur along the rim of the Pacific Ocean, called the "Ring of Fire" because of the preponderance of volcanic activity there as well.On average, a magnitude 8 quake strikes somewhere every year and some 10,000 people die in earthquakes annually.Some 80 percent of all the planet's earthquakes occur along the rim of the Pacific Ocean, called the "Ring of Fire" because of the preponderance of volcanic activity there as well.
