A fracture in the crust of a planet along which movement has occurred is a
A
mountain
B
valley
C
fault
D
river
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 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-3: -A fault is a fracture in the Earth’s crust along which two blocks of the crust have slipped with respect to each other. Faults are divided into three main groups, depending on how they move. Normal faults occur in response to pulling or tension; the overlying block moves down the dip of the fault plane.

Detailed explanation-4: -An earthquake is the sudden movement of Earth’s crust. Earthquakes occur along fault lines, cracks in Earth’s crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up.

Detailed explanation-5: -Faults. Faults are fractures in the crust along which appreciable displacement has occurred. This displacement can occur at the surface (surface rupture) or at depth (rupture area) or both. Movement can be horizontal and/or vertical.
