← GeographyWhich outcome results when lahar deposits lack sorting?
A)Diminished stream channel carrying capacity✓
B)Enhanced infiltration supporting vegetation
C)Reduced sediment available for terraces
D)Increased channel gradient along rivers
💡 Explanation
When lahars lack sorting, inconsistent particle sizes increase surface roughness, prompting rapid friction increase, therefore the stream carrying capacity decreases because energy dissipates quickly, rather than creating sediment sorting and terraces.
