Which erosional outcome occurs when a meandering river channel nears a geologic fault line?

💡 Explanation

When a river meander approaches a fault line, enhanced erosion occurs because the weakened rock structure accelerates bank collapse, shortening the meander neck, thereby accelerating the oxbow formation. Therefore faster oxbow formation occurs through neck cutoff, rather than terrace formation, or increased gradient, which operate independently of meander incidents.
