| stress | a force that acts on rock to change its shpe or volume |
| types of stress | tension, compression, and shearing |
| action of tension | stretches rock so that it becomes thinner in the middle |
| action of shearing | pushes masses of rock in opposite directions, in a sideways movement |
| action of compression | rock is squeezed until it folds or breaks |
| fault | a break in Earth's crust where masses of rock slip past each other |
| location of most faults | plate boundaries |
| types of faults | normal, reverse, thrust, strike-slip |
| normal fault | hanging wall moves down |
| reverse fault | hanging wall moves up |
| thrust fault | hanging wall moves up and over foot wall |
| strike-slip | hanging wall and foot wall slip sideways past each other with little up or down motion |
| fold | a bend in the rock |
| anticline | an upward fold |
| syncline | a downward fold |
| plateau | a large area of flat land elevated high above sea level |
