Answer to Question 1

Folds--Rock layers, when in compression, deform into folds. Folding is permanent. Most folding probably occurs deep in the crust where pressure and temperature are high and rocks are more ductile than they are at or near the surface.

Joints--Under some circumstances rock layers will fold, but if they are brittle they may respond to stress by fracturing. Joints are fractures along which no movement has taken place parallel to the fracture surface. A joint may open up, but the rocks on opposite sides of the fracture do not move up, down, or laterally along the fracture.

Faults--Faults occur when energy is suddenly released, usually as the result of displacement of rocks. On faults, blocks on opposite sides of the fracture move parallel with the fault surface. So, in the case of faults, blocks of rocks move up, down, or along the fracture
surface.
