what type of plate boundary
There are three main types of plate boundary: divergent, convergent and transform. Plates move away from one another at divergent boundaries. This happens at mid-ocean ridges. Plates move towards one another at convergent boundaries; one plate is forced below another in a process called subduction. Earthquakes and composite volcanoes are common at this type of boundary. Plates move past on another at transform boundaries. The most famous example of this type of boundary is the San Andreas Fault in California.
