Which outcome results when stream avulsion shortens a river meander?

💡 Explanation

Oxbow lake formation happens because stream avulsion cuts off a meander through channel abandonment; this is the **meander cutoff** mechanism. This form oxbow lakes quickly, rather than slower processes of erosion forming them gradually, or impacting drainage elsewhere.

• Which mechanism causes enhanced tsunami amplitude when seismic waves shoal the coast?
• Which outcome results with enhanced ventifact formation because vegetation disturbance modifies desert wind patterns?
