Sometimes tectonic plates do not move easily past one another, and the plates become stuck. Forces build up, and when the plates finally move, tension is released, as shown below. The sudden movement of the plates is caused by -

• the mass of the plates

• the weight of the plates

• unbalance forces

• gravitational force
