← HistoryWhich limitation affected Incan terrace agriculture during El Niño?
A)Increased soil salinization rates
B)Reduced nitrogen fixation efficiency
C)Slope instability becomes widespread✓
D)Decreased irrigation canal capacity
💡 Explanation
Slope failure increases, because the infiltration of excess rainwater during El Niño saturates the terrace soil exceeding the *shear strength* limit, therefore destabilizing the slopes and causing landslides, rather than directly reducing soil nutrients or damaging canals.
