Which outcome occurs when a glacial outburst flood rapidly decelerates?

💡 Explanation

Increased varve formation arises from rapid sediment settling via fluid dynamics; the settling velocity decreases as the floodwaters slow. Deposition is due to Stokes Settling because less energy is maintaining suspension, therefore sedimentation increases, rather than ice or wind changes.
