Plate Tectonic Theory: Plates and Interplate Relationships
http://csmres.jmu.edu/geollab/Fichter/PlateTect/plates.html Competition: low
Subduction zones generate lots of igneous magma that rises to the surface to form volcanic mountains (volcanic arcs; also island arcs, such as the islands of Japan, or Sumatra, or the Aleutian islands off Alaska). Thus, any time there is a divergent plate boundary where two plates are separating, there must be a convergent plate boundary (subduction zone) where two (or more) places come together again

At a depth of about 100 miles (160 km) materials in the subducting plate begin to approach their melting temperatures and a process of partial melting begins.

The theory states that Earth's outermost layer, the lithosphere, is broken into 7 large, rigid pieces called plates: the African, North American, South American, Eurasian, Australian, Antarctic, and Pacific plates. The plates are all moving in different directions and at different speeds (from 2 cm to 10 cm per year--about the speed at which your fingernails grow) in relationship to each other

Volcanoes that were formed in this way are normally found along the edges of continents, such as in the Andes Mountains of South America, or rising from the ocean floor, such as the islands of Japan. Our current drilling techniques can only penetrate approximately 6 miles (10 meters) into the crust, while the magma of the Hawaiian volcano Kilauea originates at depths of at least tens of miles (or at least 20 kilometers)
