Plate Tectonics

The movement of the lithospheric plates causes the creation of mountain ranges and mid-ocean ridges. Volcanic eruptions are also caused by the lithospheric plate movement.

Lithospheric Plates

A series of crustal plates cover Earth's surface.

Underneath the plates, convection currents cause them to move in different directions.

Radioactivity deep in Earth's mantle is causing the convection currents.
