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 ...

or slide under that plate. A collisional boundary occurs where two land masses on plates are pushed together. Trying to occupy the same space, the land masses buckle and fold, creating mountain ...

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 magnitude 7.7 earthquake was powerful, shallow and in a heavily populated region with vulnerable buildings.

believed to have been created by a cosmic collision 4.5 billion years ago, may be responsible for modern plate tectonics. In their study, published in the journal Geophysical Research Letters ...

The India-Asia continental collision and the uplift of the Tibetan Plateau have long been attributed to continuous Cenozoic convergence with two generic assumptions: the ongoing India-Asia collision ...

Earthquakes. A short video for 11-14 year old pupils, exploring tectonic activity and earthquakes and featuring case studies ...

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.
