Plates diverge and pull apart. As a gap appears lava can escape in a line where oceanic crusts ora mid-oceanic ridges form. Here mild earthquakes occour and volcanoes can be found.
1 of 5
Destructive plate boundary
Continental and oceanic plates overlap. As plates meet, the oceanic is forced down in the subduction zone. This forms volcanoes, earthquakes, fold mountains.
2 of 5
Conservative plate boundary
Two plates slide past each other. Severe earthquakes occour but volcanoes cannot be formed.
3 of 5
Collision plate boundary
These occour between converging continental plates that cannot be destroyed. Thus land is pushed upwards forming mountains and earthquakes but volcanoes cannot be formed.
4 of 5
Plate boundaries
The edges of plates - broken areas on the crust of the Earth.
