Unconformities

Unconformities are surfaces in the Earth's layers that represent a gap in the geological record, often caused by erosion or a period of no deposition. They indicate times when rocks were worn away or not formed for a period, creating a break between different layers of sediment or rock. When new layers are deposited over these breaks, it signifies a change in environmental conditions or time gaps, helping geologists understand Earth's history and the processes that shaped its surface.
