Which landform is evidence of erosion by waves on rocky coasts? (1 point)
Responses
A sea arches
B shallow ponds
C U-shaped valleys
D sand dunes
To determine which landform is evidence of erosion by waves on rocky coasts, let's analyze each option:
A) Sea arches: Sea arches form when wave erosion caves in a section of coastal rock, forming a tunnel-like structure. This is a result of wave action, making it a possible answer.
B) Shallow ponds: Shallow ponds are not typically associated with erosion by waves on rocky coasts. Therefore, this option is less likely to be the correct answer.
C) U-shaped valleys: U-shaped valleys are formed by the slow movement of glaciers, not erosion by waves on rocky coasts. This option is unrelated to the question.
D) Sand dunes: Sand dunes are formed by wind action, not erosion by waves. This option is also unrelated.
From the analysis, it can be concluded that the correct answer is A) sea arches. Sea arches are a distinct landform resulting from the erosive power of waves on rocky coasts.
