← GeographyWhich outcome results when significant tephra deposition reduces stream capacity?
A)Braided stream pattern adoption✓
B)Increased floodplain sedimentation rate
C)Decreased channel sinuosity index
D)Entrenched meander development speed
💡 Explanation
Braided streams adopt multiple shallow channels because of sediment (tephra) overload causing aggradation; therefore a braided pattern forms, rather than increased bank erosion or flow concentration since deposition is widespread and reduces the stream's erosive power.
