Shoreline Erosion and Deposition

1- Beach

Beach- waves carry different materials (rocks, sand, shells etc)
and deposits them on the shoreline

2- Sea Cave

• Sea caves- waves erode large holes in weak
rock along the base of a cliff

3- Sea Arch

Sea arch- forms
when waves
erode
a sea cave and
cut
completely
through
the rock

4- Sea stack

Sea stack- Wave erosion
creates
an isolated column of
resistant (strong) rock

5- Headland

Headland- finger-shaped
projection formed when cliff
of hard rock erode more
slowly than the surrounding
land

6- Wave Cut Sea cliff

Sea cliff- wave
erosion
undercuts rock
producing
steep slopes.

7- Barrier spit (spit)

Barrier spit- is caused
by
deposition when a
sandbar
is connected to the
shoreline

8- Barrier Island

Barrier Islands-
created when sand
is deposited by
waves offshore

9- Sandbar

Sandbar- created by deposition after material is eroded from the
Shoreline and deposited offshore

10. Wave-cut terrace

Wave cut terraces are formed when a sea cliff is
worm back by waves (they form under the water)
