Which process limits alluvial fan deposition at a tectonic basin's distal edges?

💡 Explanation

When entering a basin's distal edge, stream gradient decreases significantly because energy dissipation reduces sediment transport capacity, promoting sediment deposition. Therefore reduced transport capacity limits deposition, meaning the energy is too low for deposition, rather than base level changes, sediment grain size, or vegetation changes which are less directly related to the fans energy input/output.
