What is a fault?
A
A crack in a plate.
B
Where two plates move toward each other.
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Faults are cracks in the earth’s crust along which there is movement. These can be massive (the boundaries between the tectonic plates themselves) or very small. If tension builds up along a fault and then is suddenly released, the result is an earthquake.

Detailed explanation-2: -A fault is a fracture or zone of fractures between two blocks of rock. During an earthquake, the rock on one side of the fault suddenly slips with relative to the other. The faults are most commonly found around the edge of plates which are continental-size blocks of rocks that comprise the outermost part of the earth.

Detailed explanation-3: -A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake-or may occur slowly, in the form of creep.

Detailed explanation-4: -A fault is formed in the Earth’s crust as a brittle response to stress. Generally, the movement of the tectonic plates provides the stress, and rocks at the surface break in response to this.

Detailed explanation-5: -There are three main types of fault which can cause earthquakes: normal, reverse (thrust) and strike-slip.
