Which outcome arises when ancient Inca agricultural terraces experience cyclical freeze-thaw events?

💡 Explanation

When Inca terraces undergo freeze-thaw, cryoturbation occurs because water expands upon freezing within the soil pores, disrupting the soil structure and leading to increased pore size. Therefore nutrient leaching results, rather than increased sequestration, reduced infestations, or improved retention which require stable soil conditions.
