Which of the following is correct regarding the moment magnitude scale-a scale which quantifies the amount of energy released by an earthquake?
A) It is a scale of magnitude based on arithmetical progressions (1,2,3,4, etc.).
B) It is a closed scale that begins at 0.0 and ends at 10.0.
C) It considers the amount of fault slippage produced by the earthquake, the size of the surface (and subsurface) area that ruptured, and the nature of the materials that faulted.
D) It is the same as the Mercalli scale.

The moment magnitude scale takes into account the amount of fault slippage produced by the earthquake, the size of the surface (and subsurface) area that ruptured, and the nature of the materials that faulted. It is not based on arithmetical progressions (A) or a closed scale that begins at 0.0 and ends at 10.0 (B). It is also not the same as the Mercalli scale (D).
