| Stress | is the force that acts on rocks to change the shape and size of the rock. |
| Compression | stress that pushes rock together |
| Tension | stress that pulls rock apart |
| Shearing | stress that causes rocks to slide past each other |
| Normal fault | caused by tension, divergent boundary, foot wall slides up, hanging wall moves down. |
| Reverse fault | caused by compression, convergent boundary, foot wall slides down, hanging wall moves up |
| Strike-slip fault | caused by shearing, transform boundary, rocks slide past each other |
| elastic rebound | the energy is stored and then rocks spring back |
| aftershocks | small earthquakes after main quake |
| foreshock | small earthquakes before main quake |
| creep | slow steady movement along a fault |
