Which process predominates during pedogenesis in arid environments?

💡 Explanation

Upward capillary action is dominant because high evaporation rates draw moisture and dissolved minerals from the water table towards the surface, therefore leading to the accumulation of salts, rather than leaching as in wetter climates.
