"Waves act like a horizontal saw which makes a wide cut into the land, extending above and below the level of still water. The portion of the land above the cut breaks away and forms a sea cliff, along the foot of which stretches a level of gently sloping submerged platform or wave-cut terrace." -Dryer, 1901
