Which mechanism causes decreased stream meandering with increased gradient?

💡 Explanation

Increased stream gradient enhances water flow and shear stress exceeds the cohesive strength of bank sediments, therefore increasing erosion, rather than allowing the lateral migration associated with meandering because lower shear rates permit deposition.
