Which topographic feature increases when sediment grain size decreases within the fan region?

💡 Explanation

Frequency will increase. Finer grains allows mudflows, decreasing the sediment yield required to initiate them. Because fluid cohesion increases, these flows will therefore become common relative to channelized flows, rather than causing more incision.
