Did you feel that? Earthquakes can be so small that you can barely feel them — or they can be so strong that they topple buildings. In this BrainPOP UK movie, Tim and Moby introduce you to the mechanics of earthquakes. They’ll tell you why earthquakes happen plus what plates, faults, and waves have to do with it all. You’ll learn why the crust of the Earth isn’t as stable as it seems, what can happen on a fault line, and the names for the three types of seismic waves. You’ll also find out how scientists use seismographs to measure the strength of earthquakes. Take cover!
