Which soil degradation risk increases when terraced hillside rice farming lacks sufficient structural maintenance?

💡 Explanation

Increased water erosion emerges, because decreased terrace integrity cannot dissipate kinetic energy; terrace collapse increases surface runoff velocity, therefore amplifying erosive power onto unprotected soil surfaces, rather than promoting controlled water infiltration.

• Which outcome was LEAST likely to result from poorly-maintained terrace systems in pre-Columbian Andean agriculture?
• Which risk increases when a Roman aqueduct's settling tank experiences turbulent inflow?
• Which outcome occurred in 18th-century ship timbers that underwent prolonged cyclical submersion near the waterline?
• Which outcome resulted from increased pyrophoric weapons usage, degrading ship timbers?
• Which outcome occurred when early Mesoamerican chinampa farmers densely cultivated maize crops without crop rotation?
• Which outcome occurred at high altitudes from miscalculation on the Inca quipu?
