← GeographyWhich outcome is enhanced during lahar initiation due to colluvial soil presence?
A)Increased flow momentum and distance✓
B)Decreased infiltration and flow velocity
C)Reduced flow viscosity and stability
D)Promoted channel incision and stabilization
💡 Explanation
Increased flow momentum occurs due to bulking. Colluvial soil causes entrainment, increasing mass, therefore rising momentum extends lahar reach rather than alternative stabilization, infiltration or viscous reduction that counteracts colluvial mixing and energy loss.
