Which process contributes to the accelerated shrinking or disappearance of an oxbow lake in an arid climate?

💡 Explanation

When an oxbow lake exists in an arid environment, capillary action in the surrounding sediment increases because the pore spaces draw water to the surface faster than recharge, amplifying evaporation by increasing the surface area exposed to dry air. Therefore, capillary action accelerates shrinking results, rather than groundwater reduction, loess deposition or sinuosity effects which lead to altered flow direction or require wetter or geological sediment.
