Based on geographical analysis, geologists identify prehistoric slope failures by studying topography, rock distribution, and the geometry of geologic structures.
This is because the geometry of geologic structures reveals the primary and secondary structures of geological features like rocks.
The primary structure reveals information about the beginning of geological feature like rock mass, while the secondary structure reveals information about the deformation of the geological feature.
Hence, in this case, it is concluded that the correct answer is "geometry."
