Define the term 'erosion'
The movement of sand, soil and matter away from a certain place
The grinding of tectonic plates leading to earthquakes
The depositing of sand, soil and matter at a certain place
Sun warms up water causing it to turn into gas.
Define the term 'deposition'
The movement of sand, soil and matter away from a certain place
The grinding of tectonic plates leading to earthquakes
The depositing of sand, soil and matter at a certain place
Sun warms up water causing it to turn into gas.
Erosion can take place both at a very rapid and destructive speed or at a slower pace over a longer period of time.
True
False
In the case of a destructive wave, which part of the wave is stronger?
the swash
the backwash
the beach
the height of the wave
In the case of a constructive wave, which part of the wave is stronger.
the swash
the backwash
the beach
the height of the wave
Using the diagram choose the term that best describes 'long shore drift'?
It is when the backwash of a wave is stronger than the swash
When sand is deposited through the action of wind creating new landforms,
It is when the swash is much stronger than the backwash leading to the formation of new beaches
When sand is washed up onto the beach at an angle then pulled back into the ocean through the backwash. Sand is moved along the shore in a zig-zag pattern which can lead to erosion.
What two ways or techniques, can governments and environmental scientists use to halt, prevent, or slow down coastal erosion?
Hard and soft engineering
Concrete and Rock Engineering
Time and Money
Plastic and Composite Engineering
What preventive measure to coastal erosion am I?
Groynes
Beach fences
Rock walls
Beach nourishment
In the winter months at Quinns beach, what types of waves tend to erode the coastline?
Constructive Waves
Groyne Waves
Destructive Waves
Calm Waves
What erosion prevention technique am I?
Beach Fences
Groynes
Beach vegetation to stabilise dunes
Sea Wall
What erosion technique am I? (Choose 2)
Beach Fences
Beach Reprofiling
Groynes
Beach Re-nourishment
