Question

the picture below shows ocean water as it approaches the shore. observe the two arrows that are parallel.
text alternative
what do the parallel arrows in the illustration represent?
a) wind erosion
b) a longshore current
c) beach abrasion
d) the rounding and sorting of sand

Explanation:

To determine what the parallel arrows represent, we analyze each option:

• Option A (wind erosion) involves wind - driven processes, not ocean - related current arrows near the shore.
• Option B (a longshore current) is a current that flows parallel to the shore. The parallel arrows in the illustration of ocean water approaching the shore are consistent with the direction of a longshore current.
• Option C (beach abrasion) is the wearing down of the beach by sediment, not represented by parallel flow - like arrows.
• Option D (the rounding and sorting of sand) is a process of sediment modification, not shown by parallel arrows indicating flow.

Answer:

B) a longshore current
