Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The stress force that pulls on the crust and thins rock in the middle is ____
A
tension
B
shearing
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Tension-the stress force that pulls the crust, stretching rock so that it becomes thinner in the middle. Compression-the stress force that squeezes rock until it folds or breaks. Deformation-any change in the volume or shape of Earth’s crust. Fault-a break in Earth’s crust where slabs of crust slip past each other.

Detailed explanation-2: -Tension: Stress which occurs when rock pulls apart or gets longer. Shear Stress: Stress which occurs when tectonic plates move past each other causing rock to twist or change shape.

Detailed explanation-3: -Tension is the state of being under stress, or more specifically in this case when the Earth’s crust is under stress. Tension often occurs along continental plates and is a strong force which drives plates apart under the ocean as well.

Detailed explanation-4: -Tensional stresses cause a rock to elongate, or pull apart. Shear stresses causes rocks to slip past each other.

Detailed explanation-5: -10.6b: Tensional forces cause stretching and thinning of the rocks, usually accompanied by tensional faults.
