the action of stretching something tight
stress that squeezes rock until it folds or breaks
Stress that pushes masses of rock in opposite directions, in a sideways movement.
an inclined fault in which the hanging wall appears to have slipped downward relative to the footwall
the upper wall of an inclined fault
The block of rock that forms the lower half of a fault
a geological fault in which the upper side appears to have been pushed upward by compression
a type of fault where rocks on either side move past each other sideways with little up or down motion
a fold in rock that bends upward into an arch
