Bays.

An example of concordant bay is Lulworth cove in the Purbeck coast, as this bay was made when the waves found a weakness in the hard, limestone rock thus being able to errode that away. Once this hard rock was eroded the waves could then start to remove the soft, shale and clay rock. As this rock is softer than limestone, it is more easily eroded, and when the waves had erroded this soft rock it encountered chalk, which is a hard rock, that it could not errode. This feature is called a bay. The hard rock that is pointing into the bay is hard to errode so stays there, and this is what we call a headland.
