What is Unconformity? It represents a long period when deposition stopped, erosion occurred, and deposition resumed. The task of matching up rocks of similar age in different regions.

One of the ways history is commonly divided is into three separate eras or periods: the Ancient Period (3600 BC – 500 AD), the Middle Ages (500 -1500), and the Modern Era (1500-present).
