Correct Response: C. Strike and dip measurements are the conventional data that a geologist collects to report a geologic layer's bedding orientation in terms of the cardinal directions and the horizontal plane. An imaginary vertical plane is not referenced in recording the orientation of geologic strata (B). The depth below the land surface of the limestone strata exposed in the road cut (A) is not relevant information for reporting the bedding orientation of the limestone strata. While the thickness of a limestone bed is recorded in the field if possible, the original orientation of the bedding (D) is an interpretation of geologic history that is not typically part of mapping the orientation of geologic strata.
