The Earth’s surface may seem motionless most of the time, but it’s actually always moving, ever so slowly, at a scale that is difficult for humans to perceive. The Earth’s crust is broken up into a series of massive sections called plates. These tectonic plates rest upon the convecting mantle, which causes them to move. The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains.
