An earthquake is when the ground shakes this happens cause the plates underground move

Underground the earth has cracks called fault rocks get stuck and like that it breaks causing a seismic wave 

HEY! friends do you wanna learn some words to help you learn more about earthquakes?

Epicenter is right above the focus

Primary wave the fastest shaking wave

Surface wave causes the most damage on the ground
