Which erosional result characterizes coastlines when sand barriers impede wave energy?

💡 Explanation

Salt marsh creation occurs because the reduced wave energy behind the barrier promotes sediment deposition and colonization by marsh plants, triggering ecological succession. Therefore, salt marshes develop, rather than canyon carving that require focused flow or headland erosion from increased wave action.
