| stress | a force that acts on rock to change its shape or volume |
| tension | a stress force acting on rock that pulls on the crust, stretching rock so that it becomes thinner in the middle |
| compression | a stress force acting on rock that squeezes the rock until it folds or breaks |
| shearing | a stress force acting on rock that pushes a mass of rock in two opposite directions |
| normal fault | a type of fault where the hanging wall slides downward; the footwall slides upward; caused by tension in the crust; F-U-N |
| hanging wall | a block of rock that forms the upper half of a fault |
| footwall | the block of rock that forms the lower half of a fault |
| reverse fault | a type of fault where the hanging wall slides upward; the footwall slides downward; caused by compression in the crust; F-D-R |
| strike-slip fault | a type of fault where rocks on either side move past each other sideways with little up-and-down motion; caused by shearing in the crust |
| anticline | an upward fold in rock formed by compression of Earth's crust |
| syncline | a downward fold in rock formed by compression in Earth's crust |
| plateau | a landform that has high elevation and a more or less level surface |
