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 ...

To learn why, where, and how earthquakes happen, you need to familiarize your students with the interior of the Earth and a model called plate tectonics. The engine behind the earthquake machine ...

This program explores the composition of our Earth, and delves deep into the tectonic plates, their history and the different types of processes and landforms that occur at each boundary. Watch all ...
