Which hazard increases where tectonic uplift causes braided stream deposition into large alluvial fans?

A)Increased frequency of debris flows
B)Decreased aquifer recharge rates
C)Higher geyser eruption probabilities
D)Diminished playa lake evaporation

💡 Explanation

Increased tectonic activity and stream deposition cause steepened gradients, leading to frequent debris flows because the increase in loosely consolidated sediment becomes unstable. Therefore the hazard increases rather than a change in the aquifer or other water systems.
