The chalk cliffs at Dover and on the opposite side of the English Channel have been continually eroding since the last glaciation, at which time the English Channel was a river valley and the southern North Sea was land.

When the ice melted, the southern North Sea flooded and burst through the gap causing a catastrophic flood, which started the main erosion of the chalk cliffs and it has widened ever since.
