What Is a Geologic Fault? Windows to the Universe

A fault is a crack in the Earth's crust. Typically, faults are associated with, or form, the boundaries between Earth's tectonic plates. In an active fault, the pieces of the Earth's crust along a fault move over time. The moving rocks can cause earthquakes.Inactive faults had movement along them at one time, but no longer move.
