Which process MOST accelerates alluvial fan formation at a fault-bounded mountain front?

💡 Explanation

When mountain front experiences rapid tectonic uplift, increased gravitational potential energy causes amplified mechanical erosion and sediment supply directly into adjacent basin because runoff has greater erosive power. Therefore, the rapid uplift greatly accelerates alluvial fan progradation, rather than decreased weathering (which requires long timescales),vegetative stabilisation or reduced flow (which would inhibit fan creation).
