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

For more on divergent boundary, go to The Sea Floor Spread. Also known as subduction boundary, a convergent boundary occurs where one plate slides under another as the two are pushed together.

The results also raise uncertainty about when plate tectonics started on Earth. If Earth's first continents formed by subduction, that meant that continents started moving between 3.6 to 4 billion ...

In regions of convergence, one plate can sink under another in a subduction zone, or two colliding plates can form a mountain belt. At divergent boundaries, plates move away from each other and ...

Oceans are not necessarily a permanent fixture on Earth, as they are able to appear and close due to the work of plate tectonics. More specifically, subduction zones — where tectonic plates slip ...

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 ...
