Which risk increases within a fault-bounded basin when tectonic activity elevates surrounding mountains?

💡 Explanation

Increased tectonic uplift intensifies erosion, resulting in higher sediment yields entering the basin which accelerates alluvial fan aggradation because sediment transport capacity increases. Therefore, the fan expands rather than the floodplain improving soils, regional recharge increasing, or dune stabilization strengthening.

• Which risk increases when coastal hydro-engineering prevents upwelling?
• Which geographic feature results when prevailing wind encounters an obstacle, reducing its velocity and causing increased alluvial deposition?
• Which long-term outcome accelerates when pedogenesis limits organic matter?
• Which consequence results when increased sediment load overwhelms channel capacity in a proglacial stream?
• Which consequence results when seasonal monsoon-driven overland flow concentrates along topographic lows during intense weathering of coastal basalt rock formations?
• Near river floodplains, which process results in loess accumulation?
