Which of the following does NOT impact size and strength of waves:
Wind strength
Length of fetch
How long the wind has been blowing
Sediment load
A (a) coastline is where rock strata run parallel to the coast.
In which direction does the swash approach the beach?
From the south west
Parallel
Same as the wind
Perpendicular
With a (a) wave, the swash is stronger than the backwash.
A (a) is a drowned u-shaped glacial valley.
Isostatic change occurs much more (a)
than eustatic change.
This happens when the waves don't have enough energy to carry sediment:
Erosion
Deposition
Swash
Backwash
The type of erosion that occurs when rocks or pebbles bang together is:
Attrition
Abrasion
Hydraulic action
Solution
Solution is when salts and other acids in seawater slowly dissolve a cliff.
True
False
The feature identified is called a:
(a)
