1
Coastal Landforms around Fairlight Head
2
Joints / Geos / Inlets Wave attack picks out weaknesses in the cliff Hydraulic action (compression of air in cracks) & abrasion (pebbles as ammunition) widen the weaknesses With time the weaknesses are both widened & deepened
3
Cave Weaknesses are through time are widened & deepened dramatically
4
Cave & Arch In places the cave retreat punches through to the other side of a headland & creates a Natural Arch.
5
Cliff & Wave Cut Platform Wave attack constantly erodes the cliff base, creating a Wave Cut Notch. As the cliff is undercut, it collapses, leaving rockfalls on the beach below. As the cliff retreats it leaves behind a gently sloping platform – Wave Cut Platform
6
Headland Headlands exist, usually, because the geology of the area is resistant. The adjacent bay is, usually, soft geology.
7
Beach Fairlight Head (Headland) Beaches are a depositional feature. Erosion of the headlands produces sediment. LSD transports this sediment along the coast. The beach represents the transport of the beach & sediment movement.
8
Soft Geology Cliff Fairlight Cove is mostly softer rocks. These rocks are less resistant to erosion & landslips are common
9
Rotational Slumping The full extent of (rotational) slumping can be seen on the west side of the cove.
10
Mass Movement This is a combination of a rockfall & earthflow
