What is the role of wave refraction in tombolo formation?
Answer and explanation
Correct answer: It creates a low-energy zone behind an island and promotes deposition
Wave refraction bends wave fronts as they approach an island, concentrating energy on exposed sides but reducing wave energy in the sheltered zone behind it. Longshore movement then carries sediment into this calmer area, where deposition gradually builds a sand or shingle ridge linking the island with the mainland. Therefore, option A is correct; the other options describe unrelated river, glacial, or karst processes.
