Question

which feature causes a gap in the geologic record?
o extrusion
o fault
o intrusion
o erosion

Explanation:

Erosion removes rock layers, creating a gap in the geologic record by destroying evidence of past geological events. Extrusion and intrusion are processes of igneous rock formation that don't directly cause gaps in the record. A fault is a fracture in rock and doesn't inherently create a gap in the geologic record like erosion does.

Answer:

erosion
