This document discusses different types of plate boundaries including divergent boundaries where plates move apart, convergent boundaries where plates collide, and transform boundaries where plates slide past one another. It provides examples of each boundary type and describes the geological features and processes associated with each, such as the formation of oceanic trenches and volcanic island arcs at convergent boundaries, and the development of rift valleys and oceanic spreading ridges at divergent boundaries. It also discusses examples of hotspots, which are volcanic regions not located along plate boundaries.
