This image contains a spit, which is identified by an arrow. (The arrow is only for identification purposes.) Using the shape of the spit, from which direction is the longshore current coming? Assume for our purposes that the top of the figure is north.
A) From west to east
B) From north to south
C) From north to west
D) From south to east
Q. 2 - What erosional features, marked A and B, are visible in this figure?
A) Feature A is a headland and B is a sea cave.
B) Feature A is a spit and B is a Baymouth bar.
C) Feature A is a stack and B is a sea arch.
D) Feature A is a wave-cut bench and B is a spit.
Q. 3 - Which areas on this image will be dominated by deposition and which will be dominated by erosion?
A) Beaches will be dominated by erosion and the headland will be dominated by deposition.
B) Both the beaches and the headland will be dominated by deposition.
C) Beaches will be dominated by deposition and the headland will be dominated by erosion.
D) Both the beaches and the headland will be dominated by erosion.
Q. 4 - What process is illustrated by the arrows in this image?
A) Longshore current
B) Rip current
C) Wave refraction
D) Beach nourishment
Q. 5 - In the previous question, you had to indicate where deposition and erosion were taking place in this image. Why would deposition or erosion occur at the areas you indicated?
A) Erosion occurs where there is low water velocity and deposition occurs where there is high water velocity.
B) Erosion results from circular orbital motion whereas deposition occurs from the waves feeling bottom.
C) Erosion occurs where the water is shallow and deposition occurs where the water is deep.
D) Erosion occurs where there is high water velocity and deposition occurs where there is low water velocity.
Q. 6 - What coastal erosion feature is visible in this image?
A) Sea stack
B) Estuary
C) Wave-cut platform
D) Sea arch
