Which outcome results when a tectonic uplift increases the gradient of a river feeding an alluvial fan?

💡 Explanation

When the gradient is increased, flow velocity rises, increasing sediment transport energy because stream power steepens, resulting in deposition of coarser material further down the alluvial fan. Therefore sediment coarsening occurs, rather than avulsion, delta formation, or increased weathering which require different flow dynamics or sediment input.
