Which erosional outcome accelerates when Inca terracing lacks maintenance?

💡 Explanation

Hydraulic action increases because impaired terrace drainage concentrates erosive water flow, leading to slope instability and wall collapse. Therefore, undercutting accelerates, rather than wind erosion or loess deposition which require different environmental triggering conditions.
