Convergent Boundaries are when land mass collides, the crust crumbles and buckles into mountain ranges. When India and Asia crashed 55 million years ago, they formed the Himalayas mountains. The mountain is still growing its grows about 1 inch a year. Mount Everest is the tallest point on earth and it still is growin They also occur where the ocean dives, in a process called subduction. The overlying plate lifts up making mountains and the diving plate melts in to lava. When the plate melts it causes volcanoes erupt. The Andes mountains to form.

In the ocean, magma from deep in the Earth's mantle rises toward the surface and pushes apart two or more plates. Mountains and volcanoes rise along on the seam an example is Mt Nyriangongo witch was formed from the African Plate. A single mid ocean system connects the world's oceans, making the ridge the longest mountain range in the world, the Pacific Plate and Nasca Plate are forming it. On land giant troughs form such as the Great Rift Valley in Africa from where the African Plate and Somali Plate are tugged apart. If the plate here continues to diverge eastern Africa will spit from the continent. It will take millions of years to happen.

Is when two plats grind past each other such as the North American Plate and the Juan De Fuca Plate. The slide past each other on a line called a fault, their is a famous fault line called the San Andres Fault in California. These can trigger dealdy earthquakes such as the 1906 one in San Francisco. It was caused when the African Plate and Jan De Fuca Plate passed by each other. There is another fault line called the Blanco, Mendocino it is located in the Mid-Atlantic ocean near California. Its was formed by the Clarion Plate and Northeast PacaficPlate.======
