Imagine you are making a pizza, you start off with the dough for the crust in a large ball. You then begin to roll out the pizza dough with a roller. The result is flattened out dough. In this scenario, what simulates the STRESS that can be applied to rocks?

A. The force exerted on the dough

A. The force exerted on the dough

B. The flattening out of the dough ball

C. The force you exert on the roller

Explanation: When it comes to rocks, stress is the force exerted per unit area. There are different forms of stress that can be applied to a rock. They are :

Confining Stress: this form of stress occurs when a rock is under the surface of the earth and has restricted movement. This is exactly like the pizza being rolled.

Compression Stress occurs at boundaries where plates in the earth crust are moving towards each other, also known as convergent plate boundaries. This action exerts force on the sides of the rock and fractures the rock.

Tension Stress occurs at boundaries where plates in the earth crust are moving away from each other, or divergent plate boundaries. Tension causes rocks to break apart by stretching the structure  of the rock.

Shear stress occurs when rocks slide against each other in a parallel motion and are common  in transform plate boundaries where plates make sliding motions.
