Earthquakes result from sudden motions along breaks in Earths crust and can affect landforms and societies An entire branch of Earth science called seismology is devoted to studying earthquakes. By. : 10 grade. What is an earthquake ?. Simply, earthquakes are the rumblings, shaking or rolling of the earth's surface. It is usually what happens when two blocks of the earth suddenly slip past one another, or break apart from each other as a result of tension caused by prolonged energy build up. . 8.53.
