Here's a breakdown:
* Fault: A fracture or zone of fractures in the Earth's crust where there has been significant movement. This movement can be horizontal, vertical, or a combination of both.
* Fault Plane: The surface along which the movement occurs.
* Fault Scarp: A cliff or step that forms on the Earth's surface due to vertical movement along a fault.
Faults are a fundamental feature of plate tectonics, the theory that explains the movement of Earth's outer layer. When these blocks of crust (tectonic plates) collide, move apart, or slide past each other, they create faults, resulting in earthquakes, volcanoes, and mountain formation.
