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. Convergent boundaries are areas where plates move toward each other and collide. 2  These are also known as compressional or destructive boundaries. 3  Subduction zones occur where an oceanic plate meets a continental plate and is pushed underneath it. 4  Subduction zones are marked by oceanic trenches.
