Which mechanism dominates stream diversion across orogenic belts?

💡 Explanation

Antecedent streams maintain course because tectonic uplift occurs slowly, allowing stream erosion through superimposition to balance crustal movement; therefore streams 'cut through' rising land, rather than divert like the lower-energy options B, C, and D.

• Which risk increases when tectonic uplift causes increased incision within a broad alluvial plain?
• Which risk increases where strike-slip faults intersect aquifers?
• Which outcome changes stalactite isotopic ratios due to precipitation?
• Which erosional outcome is accelerated when cryoturbation destabilizes a cirque headwall?
• Which risk increases when prolonged carbonic acid forms?
• Which risk drastically increases when groundwater acidity increases flowing through karst?
