9. Up until12,000 years ago, during the late Pleistocene, sea levels were lower.

Sea level fluctuated almost continuously between interglacial levels and levels during times of maximum glaciation, such as 18,000 years ago when sea level was more than 100 meters lower. Coastal environments during the Pleistocene were controlled in large part by the fluctuating level of the sea, as well as by local tectonic and environmental conditions. During the Pleistocene, sea levels dropped to levels at least 100 meters below modern sea level on at least four occasions during the last 600,000 years. These lowstands concur with glacial maxima, which demarcates the boundary between the Pleistocene and Holocene Epoch.
