Shake, rattle and roll: the tectonic plates must be shifting! In this video, we learn all about earthquakes. Below our feet is the Earth's surface, made of tectonic plates. Those plates are always moving and shifting and sometimes, this movements causes big shaking! Earthquakes can cause changes in our Earth's surface and can even be dangerous. Join us as we explore these mighty earth shakers together.
Understand that Earth is made of three layers, and the outer layer is the crust
Understand that the crust is made of tectonic plates, which join together at fault lines
Learn that earthquakes happen when tectonic plates shift or bump against one another, causing the ground to shake
Learn that the Richter scale measures the magnitude of earthquakes
Learn how earthquakes can be destructive
