← GeographyWhich outcome typically results when intersecting faults impede drainage?
A)Development of sag ponds or marshes✓
B)Increased stream sediment load capacity
C)Decreased infiltration rate into aquifers
D)Accelerated chemical weathering of bedrock
💡 Explanation
Sag ponds form due to impeded drainage along fault lines, creating depressions that trap water; vertical offset blocks flow. This occurs because fault-related displacement disrupts previous drainage patterns rather than enhancing stream capacity or changing chemical weathering rates; therefore, marshes develop.
