1. If waves enter shallow water
2. If there is not a lot of wind.
3. If the material is heavy
LANDFORMS CREATED
BY EROSION
Headlands and Bays
Arches, Caves,
Stacks & Stumps
1. Waves attack the fault which
is a weakness in the headland
2. A cave is formed, through processes of
erosion such as hydraulic action and corrasion
3. Eventually, the cave erode
through the headland to form an arch
4. The roof of the arch collapses
leaving a column of rock called a stack
5. The stack collapses
leaving a stump

SPIT IN HAMPSHIRE**
A spit is an area of sand or shingle which either extends
at a gentle angle out to sea or which grows across a river
estuary. Many spits are characterised by a hooked, or
curved end. Spits only develop in places where longshore
drift moves large amounts of material along the beach, or
if there is a sudden change in the direction of the
coastline or even if the sea is relatively shallow and
becomes progressively more sheltered.
How it is formed: Prevailing winds from
the south west. Material carried east along
the beach by longshore drift. Sand and
shingles get deposited where coastline
changes direction. Spit continues to grow
outwards. Speed of river prevents spit
growing all the way across the estuary.
