Which soil profile development is increased where groundwater fluctuates near surface?

💡 Explanation

Fluctuating groundwater increases the wet/dry cycle, which causes redox cycling. This increased oxidation and reduction causes alternating mobilization and precipitation of iron and manganese because of this pedogenesis; therefore, distinct colored bands form, rather than uniform leaching.
