a part of my GSCE Geography revision of coastal processes, I produced these
simple animations. I hope they clarify some points for you if you are studying
Geography at this level.
This is how a wave-cut platform is
made. Erosion from the sea takes place between the
"high" and "low" "water-mark". When
a large notch is formed at the base of a cliff the cliff collapses
and is taken out the sea by the tide.
Crack, cave, arch, stack, stump.
It's Geography to me.
Here is the pebble being carried
along the beach by the Longshore drift.
