Shoreline Erosion and Deposition

​Shoreline Erosion and Deposition

1- Beach

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

Multiple Choice

How is a Beach Formed?

• By the accumulation of sand from the ocean floor
• By the erosion of mountains

2- Sea Cave

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

Multiple Choice

How is a Sea Cave Formed?

• By the accumulation of sand
• By the erosion of waves

3- Sea Arch

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

Multiple Choice

How is a Sea Arch Formed?

• By the erosion of wind
• By the erosion of water
• By the accumulation of sand

4- Sea stack

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

Multiple Choice

How is a Sea Stack Formed?

• By the erosion of cliffs by the sea
• By the accumulation of sand on the sea floor
• By the deposition of sediment by rivers

5- Headland

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

Multiple Choice

How are Headlands Formed?

• By the erosion of waves
• By the deposition of sand

6- Wave Cut Sea cliff

Sea cliff- wave
erosion
undercuts rock
producing
steep slopes.

Multiple Choice

How are Wave Cut Cliffs Formed?

• By the erosion of the sea
• By the wind erosion

7- Barrier spit (spit)

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

Multiple Choice

How is a Barrier Spit Formed?

• By the deposition of sediments by the action of longshore drift
• By the erosion of coastal cliffs

8- Barrier Island

Barrier Islands-
created when sand
is deposited by
waves offshore

Multiple Choice

How is a Barrier Island formed?

• By the erosion of mainland coastlines
• By the deposition of sediment by ocean currents and waves

9- Sandbar

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

Multiple Choice

How is a sand bar formed?

• By the accumulation of sand due to wind
• By the deposition of sand by water currents
• By the erosion of rocks

10. Wave-cut terrace

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

Multiple Choice

How is a Wave-cut terrace formed?

• By the deposition of sediment
• By the action of waves on a coastline
