Whatever drives the movement, plate tectonic activity takes place at four types of boundaries: divergent boundaries, where new crust is formed; convergent boundaries, where crust is consumed ...

These convergent boundaries also occur where a plate of ocean dives, in a process called subduction, under a landmass. As the overlying plate lifts up, it also forms mountain ranges. In addition ...

Plate boundaries are where the action is ... Use Graphic 2 to discuss convergent, divergent, and transform boundaries. Explain why each of these boundaries has the particular observable phenomena ...

New crust is continually being pushed away from divergent boundaries (where sea-floor spreading occurs), increasing Earth's surface. But the Earth isn't getting any bigger. What happens, then, to ...

This is called a destructive or convergent plate boundary. When the plates collide, the denser plate, usually the oceanic one, is forced underneath the continental plate. The force of this ...
