Which mechanism causes increased stream meandering along coastlines during periods of rising sea level?

A)Hydraulic sorting shifts channel sediment load

B)Enhanced Coriolis force deflects current flow

C)Increased evaporation removes floodwater limits

D)Decreased channel slope reduces potential energy✓

💡 Explanation

When sea level rises, the base level of streams elevates because streams seek equilibrium, decreasing the overall channel gradient and reducing the downcutting potential along with associated energy thresholds. Therefore decreased channel slope results, allowing meandering to increase over other sorting, deflection, or evaporation effects that require constant base levels.
