solution
suspension
saltation

saltation
Coastal erosion can lead to significant economic impacts, particularly for communities that rely on tourism and other activities that are closely tied to the beach and the surrounding ecosystem.
True
False
What is the importance of managing coastal erosion?
To protect human communities and the environment, and to recognize that some erosion is a natural and necessary part of coastal ecosystems.
To increase economic growth and property values, and to reduce biodiversity loss.
To increase tourism, reduce flooding, and increase habitat availability.
To protect natural resources, increase ecological resilience, and decrease climate change impacts.
Letter B is called a ____.
Sea Cave
Sea Island
Sea Arch
Sea Stack
What is this type of wave?
Constructive wave
Destructive wave
What is this type of wave?
Coast building - constructive
Coast destroying - destructive
What is Hydraulic action?
The weight and impact of water against the coastline which cause cracks/caves to form.
The way a coastal feature transitions into a new feature
The time it takes for erosion to occur
The way a wave moves up the beach and interacts with the coastline.
What is the main difference between a spit and a tombolo?
A spit connects two headlands, while a tombolo connects an island to the mainland
A spit is formed by erosion, while a tombolo is formed by deposition
A spit is always curved, while a tombolo is always straight
A spit moves inland over time, while a tombolo remains stationary
What is found behind a spit where water is sheltered from waves?
A bar
A stack
A lagoon
A wave-cut platform
What coastal feature forms when a sandbar becomes separated from the shore due to rising sea levels?
Headland
Barrier island
Bay
Wave-cut platform
Identify the landform type.
Sea Stack
Sea Stump
Arch
Bay
Add the correct labels to the places
Hard or soft engineering
Sea wall
Groyne
Rock armour - or rip rap
Gabion
Dune
Managed retreat
Salt marshes
Pros and cons of hard engineering
Sea walls deflect the energy of the storm waves
Stops the waves from hitting the cliffs
Longlasting
Gabions and rock armour are relatively cheap
Seawalls are expensive
Can put a promenade at the back to walk on or for small businesses to set yp such as food stalls
Groynes can create long beaches that reduce friction and slow down the energy of the waves
Groynes can result in beach starvation further down the coast
Can sometimes be ugly
Will need replacing and repairing in the future
Pros and cons of soft engineering
Often cheap
Fits in with the natural landscape
Kinder to wildlife
Can create a wide beach to reduce friction and take energy out of the waves
Can take time to take effect
Might need replacing after storms
Dredging for beach replenishment can cause offshore damage
Low value areas are left to erode
This picture shows beach nourishment. What type of coastal management strategy is this?
Soft engineering
Hard engineering
Name the coastal management technique.
Sea wall
Gabions
Revetments
Riprap
Why are seawalls often concave?
To direct waves upwards
To reflect the waves back into the sea
To act as a slide for tourists
Which of the following is NOT an advantage of using groynes?
They work with natural processes
They build up the beach for tourism
They are relatively inexpensive
They starve beaches of material further down the coast
Hard or soft engineering?
Soft Engineering
Hard Engineering
If the photo is facing south, which direction is longshore drift working in?
west to east
east to west
south to north
north to south
