earthquakes I
... • Earthquakes occur where there are breaks in the crust of the earth. Usually there are large plates of crust that move against each other. When the plates move side by side the rubbing together makes vibrations and these are earthquakes. The sliding plates grind off pieces of rock as they move. If ...
