Vibrations produced by breaking of rocks are called vibrations, earthquakes are produced by these, earthquakes occur when the plates under the earths crust are built with stress and then collapse, causing them to move inward towards each other and cause large virations, producing earthquakes. 8th grade question.

in my science book it says an earthquake

Vibrations caused by rocks breaking and moving as a result of a sudden release of energy is called an Earthquake. By the movement of plate boundaries, depending how it moved, is how strong the Earthquake will be.

It is a seismic wave.
