__**What are plate Tectonics?:**__ Plate Tectonics make up the entire world. There are major and minor plates.Both oceans and land formations sit on these plates.


 * __Convergent Plates-__** Plates that bump into each other. Eventually they can make a new land formation, like ocean-ridges, mountains and volcanos.


 * The Himalayan Mountains were formed by convergent plates. The overlaying plate kept pushing its way over the diving plate. The diving plate melts and often forms into volcanos.


 * Convergent plates that ran into each other caused Marina Trench (North-Pacific Ocean) to be the deepest point on Earth. Underwater volcanos form and become active. They then form islands in the shape of an arch that grows every day. The arch shape is formed because the plate is moving, but the hot spot where the lava comes out never moves.


 * The philippine plate is located between two plates which both move towards it in a convergent motion. It is the location of some of the deadliest volcanoes in the world. In the last ten years there have been at least 10 earthquakes at a level greater than 7.0.

__**Divergent Plates-**__ plates that move apart from each other, using ridge push and slab pull.
