Which outcome results from high sediment input and reduced streamflow into a lake?

💡 Explanation

Delta formation occurs because high sediment input combined with a reduction in flow reduces the sediment carrying capacity and deposition at the lake increases. Delta formation follows, rather than thermohaline circulation which depends on water density differences.
