A rock pool stop for teaching wave-cut platforms, erosion and why some coastal rock surfaces look strangely flat.

South Curl Curl Rock Pool gives families a chance to talk about wave-cut platforms. These broad, relatively flat rock surfaces are shaped by repeated attack from the sea. Over long periods, waves exploit weak points, chip material away and gradually carve a bench-like edge near sea level.
The pool adds a second layer to the lesson. Humans have inserted a safe swimming space into a landform that was already telling a geological story. Children can compare the straight edges people made with the softer edges the sea created naturally. It is a neat visual contrast between natural erosion and human design.
