← GeographyWhich hazard increases near the down-sloping head of an alluvial fan?
A)Increased likelihood of channel avulsion✓
B)Decreased rates of chemical weathering
C)Reduced deposition of fine sediments
D)Lower groundwater recharge potential
💡 Explanation
Increased slope from topography steepness commonly triggers 'channel avulsion,' because sediment accumulates unevenly, therefore causing the channel to seek a steeper path rather than maintaining its current flow, rather than changing weathering or deposition alone.
