Most importantly, the scheme should now be based on all four data types. For example, boundary type A might be described as having shallow earthquakes on the plate boundary, sparse or no volcanoes ...

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 ...

When the plate sinks into the mantle it melts to form magma. The pressure of the magma builds up beneath the Earth's surface. The magma escapes through weaknesses in the rock and rises up through ...

Where convection currents push plates together, destructive plate boundaries (margins) are formed. Constructive plate margins close constructive plate marginAn area where two tectonic plates are ...

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 ...

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 ...
