← HistoryWhich risk increases when Inca terracing loses structural integrity?
A)Quipu record interpretation errors
B)Localized hypoxic soil conditions
C)Mass Gravity Downslope Movement✓
D)Increased llama wool moisture
💡 Explanation
Instability causes increased potential energy that converts to kinetic energy, because terracing supports soil mass using countering frictional forces. The mechanism is slope instability therefore, mass gravity downslope movement occurs, rather than errors related to recording, hydration or localized anoxia.
