Which outcome relating to river stream incision occurs when tectonic uplift concentrates near a major river's headwaters?

💡 Explanation

Tectonic uplift at the headwaters will cause increased stream power, triggering regressive erosion; this results in increased knickpoint migration upstream because of increased hydraulic gradient, therefore inducing channel steepening rather than depositional processes downstream.

• Which mechanism causes meandering stream patterns in low-gradient landscapes following tectonic uplift?
• Which seismic outcome occurs when locked transform faults rupture?
• Increased coastal erosion occurs when intensification alters gyre currents because of which mechanism?
• Which outcome is amplified with increased aeolian ventifact formation?
• Which mechanism primarily causes building foundation failure in regions with discontinuous permafrost when ambient temperature increases?
• Which landform results when differential erosion breaches arches in coastal headlands?
