← HistoryWhich outcome arises during an Inca agricultural terrace collapse?
A)Decreased land stability upslope above✓
B)Increased biodiversity due to water flow
C)Enhanced soil oxygen levels throughout
D)Improved overall regional crop yield.
💡 Explanation
Landslide risk increases above because the terraces employed buttressing. Erosion then escalates, diminishing soil cohesion upslope, therefore stability drops, rather than being offset by unrelated minor effects on biodiversity or regional harvest volume, and soil oxygen decline
