Which risk elevates when mechanical weathering surpasses chemical?

💡 Explanation

Increased fragment size from mechanical weathering facilitates accelerated sediment transport, because smaller particles, produced during chemical weathering, bind better; therefore, higher rates of transport result, rather than changes in nutrient availability, dissolution or exchange directly.
