Which outcome occurs when rapid crustal uplift obstructs rivers entering endorheic basins?

💡 Explanation

Alluvial fans will reform extensively because the increased bedload deposition through **aggradation** overwhelms basin capacity. This causes fan surfaces to steepen and braid, therefore a larger fan system forms, rather than simple channel incision.

• Which outcome occurs when sediment supply outpaces subsidence in a region where multiple alluvial fans coalesce?
• Which mechanism explains elevated mercury levels in soils near strike-slip faults?
• Which risk increases when prolonged drought accelerates groundwater depletion above Florida's aquifers?
• Which outcome exacerbates coastal flooding during an El Niño event due to altered atmospheric circulation?
• Which risk increases on a newly-formed volcanic island lacking vegetation?
• Which river characteristic increases the risk of avulsion within a distal alluvial fan?
