The tiny Juan de Fuca plate is largely responsible for ... The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where ...

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 ...

Sinking in one place leads to plates moving apart in other places. The movement of the plates and the activity inside the Earth, is called the theory of plate tectonics.

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 ...

Four types of plate tectonic activity are demonstrated in this feature. Keep an eye on the map to see where in the world the activity takes place. Also known as spreading boundary, a divergent ...

The diagram below shows the structure of the earth ... Where convection currents push plates together, destructive plate boundaries (margins) are formed. Constructive plate margins close ...
