Which outcome results from river channel avulsion promoting oxbow formation?

💡 Explanation

Avulsion causes the river to abandon its old channel and create a new, shorter path; this increases sediment deposition on the floodplain because of the change in flow path, therefore leading to increased deposition, rather than reduced habitat diversity.

• Which outcome occurs when granitic bedrock undergoes spheroidal weathering?
• Which landform results when isostatic rebound follows deglaciation within a fjord valley containing varying bedrock resistance?
• Which long-term effect increases when vegetation inhibits horizonation during pedogenesis?
• Which characteristic determines the settling rate of alluvial sediments as river flow decreases?
• Which effect occurs when increased meltwater influx disrupts thermohaline circulation within North Atlantic gyres?
• Which consequence results when reduced infiltration during pedogenesis weakens soil structure?
