Which consequence results when unimpeded longshore drift transports sediment?

💡 Explanation

Unimpeded longshore drift causes increased barrier island gradients because differential deposition rates cause islands to grow at varied pace parallel to the shore by sediment transport. Areas receiving sediment build out rather than remaining stable.
