Types of Plate Boundaries and their Properties.

Divergent Plate Boundaries - Divergent boundaries are areas where two plates move away from each other and the space that fills those two plates which is then filled with crust sourced from magma. This action results in forming mid ocean ridges and rift valleys. Divergent boundaries are also known as constructive boundaries. 

Convergent Plate Boundaries - Convergent boundaries occur when two (or more) plates move toward each other and eventually collide head on. The compression that follows eventually pushes the denser plate to fold under the other plate in a process called subduction. Convergent boundaries are also known as compressional or destructive boundaries. Many volcanos occur along convergent boundaries.

Transform Plate Boundaries - Transform boundaries only occur when two plates move past each other in a horizontal way. There is very limited convergent and divergent activity. Transform boundaries are also known as conservative plate boundaries because they do not result in a loss or gain of lithosphere.
