This curved indentation along the coast often makes a safe harbor for boats.
Bay
These structures are built along the coast to protect the land from the sea.
Sea walls
Name 4 types of coastal erosional processes
Hydraulic action, Abrasion, Corrosion, Attrition
A common result of a storm surge in a coastal area is this.
Flooding
When the waves do not have adequate energy, they drop the sand, pebbles and rocks they are carrying. This is called deposition.
Coastal Deposition
his isolated vertical column of rock, created when erosion cuts away a headland, is known as this feature.”
stack
This coastal defence uses wooden or stone barriers built at right angles to the beach to trap sand.
Groynes
The sheer force of waves as they compress and trap air in the cracks in the cliff and break it down
hydraulic action
This small town in Norfolk is known for its rapid coastal erosion.
Happisburgh?
True or false? Deposition occurs when Swash is weaker than the Backwash.
False
When a spit connects an island to the mainland, it is called this coastal feature.
Tombolo
Large rocks placed on the beach to absorb wave energy are called this.
rock amour
Results from breaking waves hurling rocks and pebbles on the base of the cliff, wearing it down. Known as the sandpaper effect
. abrasion
This natural force, when waves hit the shore, plays a major role in eroding the coast
coastal Erosion
True or False?
Deposition occurs when the fetch is small
True
After a big storm surge, what do coastal communities often do to keep people safe
evacuation
This method adds sand to a beach to combat erosion
Nourishment
When certain types of rocks in the cliffs are slowly dissolved by water. For eg, limestone
corrosion/solution
This natural force, when waves hit the shore, plays a major role in eroding the coast
wave action
This is a narrow piece of land that sticks out into the sea, usually made of harder rock than the surrounding coas
headland
What is one advantage of using beach nourishment as a coastal defence?
It adds sand to the beach
Strong winds help push water onto the shore, creating this surge.”
Storm Surge
When waves cause rocks and pebbles on the beach to bump into each other and wear down
attrition
This process involves the movement of sand along the coast due to the action of waves.
longshore drift
Name any two depositional landforms
Beaches and spits
