Which mechanism accelerates stream erosion as a result of increased glacial meltwater discharge?

💡 Explanation

When glacial meltwater increases, streams gain more energy because of increased flow rate, leading to elevated stream competence, meaning streams can transport larger particles. Therefore, increased sediment entrainment accelerates erosion, rather than deposition or radius changes which require reduced flow, or sinuosity change from geologic processes.
