← GeographyWhich outcome occurs when rapid tectonic uplift intersects an established alluvial plain?
A)Increased flow channel incision✓
B)Widespread deposition of loess
C)Formation of extensive karst topography
D)Accelerated chemical weathering profile
💡 Explanation
Increased flow channel incision occurs because the rapid tectonic uplift raises the base level, energizing the river's erosive power via stream rejuvenation, therefore causing deeper valleys rather than deposition or unrelated processes like karst formation in different geological settings.
