The function of strike and dip symbols is primarily related to the geometric orientation of geological layers and structures. These symbols are crucial for understanding and representing the spatial relationships between different rock strata and geological features on maps.

Strike refers to the direction of the line formed by the intersection of a geological surface with a horizontal plane, typically expressed as a compass bearing. Dip indicates the angle at which the surface descends relative to the horizontal plane, and it specifies the direction in which the layer is inclined. When these symbols are used on a geological map, they provide essential information for tracing the pattern of rock outcrops, which is pivotal for geological mapping, analysis, and understanding the subsurface geologic conditions.

This mapping allows geologists to visualize how rock layers relate to one another in three-dimensional space, contributing to interpretations regarding their history and formation. The other options relate to concepts that do not directly connect to the strike and dip symbols, as they focus on aspects other than the spatial representation of rock layers.
