Processes of erosion
and landforms
- Weathering
- Freeze thaw
- Salt crystallisaton
- Wetting and drying
- Solution
- Carbonation
- Biotic weathering - roots of
seaweed, acid secretions by
limpets/barnacles/seagulls
- Erosion
- Corrosion
- Hydraulic action
- Abrasion
- Attrition
- Landforms
- Cliffs - rocky faces that develop
along coastlines where marine
undercutting has been ongoing
- Undercutting at base leads to
wave-cut notch, collapses by fall
or slumping, progressive retreat
leads to wave-cut platform
- Caves develop where lines of weakness are
exploited, arches develop where caves erode
back to back on headlands, stacks result when
arch collapses
- Stumps remain where stacks collapse
- Landforms from rise of sea
level are either from
eustatic rise or local areas
of subsidence
- Submergence of land by an
encroaching sea causes
landforms such as rias and
fjords
- Eustatic adjustment
- worldwide change
in sea level.
Isostatic
readjustment is
localised change in
sea level due to
changes (ice
removed from land)
