Which outcome occurs when increased sediment supply interacts with wave refraction at a coastal island?

💡 Explanation

Wave refraction around an island concentrates wave energy, causing sediment deposition in calmer areas; because of longshore drift, a tombolo, a sandbar connecting the island to the mainland, is formed in the wave shadow, therefore connecting them rather than forming offshore bars.
