Destructive plates occur when the oceanic and continental plate move towards each other. The oceanic plate is forced under the continental plate.

Constructive plates are plates that move apart. As a result of this, volcanoes are formed as magma wells up to fill the gap, and eventually new crust is formed.Mid Atlantic Ridge is an example of this!

Conservative plates are two plates that slide past each other in opposite directions, or in the same direction but at different speeds.This occurs at The San Andreas Fault in California.

Collison zones form when two continetal plates collide. Nietherplate is forced under the other,and so both are forced up and form fold mountains.
