What property defines the distance between two faces of a rock defect? Group of answer choicesSpacingAperturePersistenceBedding

To determine the property that defines the distance between two faces of a rock defect, we need to understand the definitions of the options given:

1. Spacing: This refers to the distance between two similar features, such as fractures or joints, in a rock. In the context of rock defects, spacing would represent how far apart the faces of the defect are located.

2. Aperture: This refers to the width of the opening between two rock faces. It typically indicates how wide a joint or fracture is at its opening but does not necessarily imply the distance between two faces themselves.

3. Persistence: This describes how continuous a rock defect is over a distance. It measures the extent to which a defect can be traced through the body of rock, rather than the distance between faces.

4. Bedding: This pertains to the layers of sedimentary rock and the way they are deposited. It does not directly relate to the concept of defects or distances between faces.

Conclusion

The property that best defines the distance between two faces of a rock defect is Spacing. This is because spacing directly measures the distance between two such faces, making it the most appropriate choice.
