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

These convergent boundaries also occur where a plate of ocean dives ... the deepest point on Earth. These types of collisions can also lead to underwater volcanoes that eventually build up ...

subduction zones may themselves be transformed to other types of plate boundary. For example, when India collided with Asia, an active subduction zone was transformed into a collision that formed ...

The San Andreas Fault is undoubtedly the most famous transform boundary in the world. To the west of the fault is the Pacific plate, which is moving northwest. To the east is the North American ...

believed to have been created by a cosmic collision 4.5 billion years ago, may be responsible for modern plate tectonics. In ...

Plate boundaries are where the action is. A large fraction of all earthquakes, volcanic eruptions, and mountain building occurs at plate boundaries. It is also where most of the people on Earth live.

At collision zones fold mountains will be formed. These are plate boundaries where two plates are either slipping past each other in opposite directions or at different rates in the same direction.
