How does a nonconformity form? - Answers

A nonconformity forms when geological processes create a gap in the geological record, typically due to erosion or a period of non-deposition. This occurs when older rock layers are exposed at the surface, eroded away, and then subsequently covered by younger sediments. As a result, the older and younger layers do not align, creating a distinct boundary known as a nonconformity. This geological feature highlights the complexity of Earth's history and the dynamic processes that shape it.
