- normal fault
- a fault in which the hanging wall appears to have slipped downward relative to the footwall
- reverse fault
- A fault in which the hanging wall moves up relative to the foot wall
- divergent boundary
- boundary between two tectonic plates moving away from each other
- folding
- the bending of rock layers due to stress in the Earth's crust
- transform boundary
- boundary between two tectonic plates that are sliding past each other horizontally
- subduction zone
- the region where an oceanic plate sinks down into the asthenosphere at a convergent boundary, usually between continental and oceanic plates
- fault
- a break in the Earth's crust along which two blocks of the crust slide relative to one another
- convergent boundary
- boundary between two colliding tectonic plates
- plate tectonics
- theory that the lithosphere is made up of plates that float on the asthenosphere & that the plates possibly are moved by convection currents
- strike-slip fault
- a fault in which the two fault blocks move past each other horizontally
