compression
|
-rock is squeezed together
-volume is reduced -rock is pushed upward or downward found at a convergent boundary |
|
|
tension
|
-rock is pulled apart
-rock becomes thinner -rock tends to sink downward found at a divergent boundary |
|
|
shearing
|
-rock is pushed in opposite horizontal directions
-this results in bending twisting, and breaking Found at a transform boundary |
|
|
bends
|
folding
higher heat/more pressure at depth |
