describe the three types of unconformities
There are three types of unconformities: disconformity, nonconformity, and angular unconformity. Disconformity An unconformity between parallel layers of sedimentary rocks which represents a period of erosion or non-deposition.est Answer: An unconformity is a gap in time in rock layers, where erosion occurs while deposition slows or stops. The rocks above an unconformity are younger than the rocks beneath (unless the sequence has been overturned).
