The document discusses various physical and chemical weathering processes that contribute to coastal erosion. It explains how harder rocks resist erosion better than softer rocks, causing headlands to form in harder rocks projecting into the sea, while softer rocks erode to form bays. Over time, the headlands are further eroded by waves while deposition continues in the sheltered bays.

The more resistant
rock is left sticking out
into the sea called a
headland.
The softer rock is
eroded by the sea-
forming a bay.
This area is now more
sheltered, this
encourages deposition
and beaches are
formed.

Surrounded by deep
water and exposed to
the full force of the
waves- the headlands
are eroded.
The shallower waters
in the bay continue to
encourage deposition.
