Which effect accelerates longshore drift when approaching headlands?

💡 Explanation

Wave refraction bends waves toward headlands, concentrating wave energy because shallower nearshore waters decrease wave speed. Therefore, increased energy accelerates sediment transport and erosion around headlands that shapes shorelines, rather than uniform erosion.
