Which consequence results when terrace gradient is excessively steep in historical Andean agriculture?

💡 Explanation

Increased soil erosion occurs because the angle of repose is exceeded; this triggers gravitational downslope movement rather than water retention for roots, and therefore erodes topsoil faster, rather than improving infiltration and nutrient retention.
