Which outcome commonly develops due to alluvial fan processes where mountain rivers meet plains?

A)Braided stream channel formation
B)Raised sea cliff erosion
C)Increased glacial ice accumulation
D)Extensive cave karst topography

💡 Explanation

Braided streams develop because the decrease in slope from mountain to plain causes deposition along multiple, interwoven channels via the mechanism of aggradation; therefore, braided channels form rather than single, deep channels, because sediment load capacity changes.
