What is Coastal Erosion?
The conservation efforts to protect coastal wildlife
The process of building up sediment along the coastline
The removal and transport of sediment and rocks from the coastline
A type of urban development near coastal areas
Which of the following is NOT a type of Coastal Erosion?
Abrasion
Condensation
Attrition
Hydraulic Action
What role do waves play in Coastal Erosion?
They only affect the temperature of the coastal areas
They have no significant impact on coastal erosion
They break down sediment and rocks, transporting them to different areas
They deposit large amounts of sediment on the shore
What can increase the frequency of Coastal Erosion?
Decreasing the amount of rainfall in coastal areas
Human-induced activities and climate change
Planting more trees along the coastline
Building more coastal defenses in one place which reduces the beach further down the coast
Which type of wave is most associated with causing erosion?
Tidal waves
Standing waves
Destructive waves
Constructive waves
What is the result of the constant occurrence of coastal erosion?
Expansion of coastal land area
Development of different landforms
Decrease in ocean water levels
Increase in coastal wildlife
What is Abrasion in the context of Coastal Erosion?
The dissolving of sediment by acids in seawater
The grinding of rocks and pebbles into each other
Rocks and sand hitting the cliff, causing the wearing down of the rock
The compression of air in cliff crevices by waves
How does Hydraulic Action cause Coastal Erosion?
By the deposition of large amounts of sediment
By grinding rocks and pebbles into each other
By compressing air in cliff crevices, eroding surrounding rocks
By dissolving sediment that reacts with acids in seawater
What is a long-term effect of Coastal Erosion?
Immediate increase in land area
Instant formation of new coastal landforms
Rapid urban development
Shaping the landscape over years or decades
Which is NOT a driver of Coastal Erosion?
Waves and tides
Increased coastal vegetation
Wind and weather patterns
Construction along coastlines
