Which pedogenesis effect increases in seasonally flooded terrains?

💡 Explanation

Gleying occurs because cyclical water saturation inhibits oxygen diffusion into the soil, resulting in anaerobic conditions supporting iron reduction; therefore, gleying appears, rather than calcification, which requires prolonged dry phases and evaporation.
