Final answer:
Divergent plate boundaries occur when two plates are moving away from each other, creating seafloor spreading and mid-ocean ridges. Convergent plate boundaries occur when two plates are moving toward each other, creating mountain building and mountain belts. Transform plate boundaries occur when two plates slide past each other horizontally, creating earthquakes and faults.
Step-by-step explanation:
Divergent plate boundaries occur when two plates are moving away from each other. An example of this type of movement is the Mid-Atlantic Ridge, where the North American plate and the Eurasian plate are moving apart. At this boundary, there is an ocean-ocean convergence, as both plates have oceanic crust. The type of activity that occurs at this boundary is seafloor spreading, where new oceanic crust is formed. Features found at this boundary are mid-ocean ridges.
Convergent plate boundaries occur when two plates are moving toward each other. An example of this type of movement is the collision between the Indian plate and the Eurasian plate, forming the Himalayas. In this case, the boundary has a continent-continent convergence, as both plates have continental crust. The activity that occurs at this boundary is mountain building and the creation of mountain belts. Features found at this boundary are mountains.
