← HistoryWhich outcome occurred when pre-Columbian terraces at Angkor suffered deforestation?
A)Decreased sediment capture efficiency✓
B)Enhanced nitrogen fixation in soil
C)Strengthened embankment structural integrity
D)Improved overall water infiltration rates
💡 Explanation
Decreased sediment capture efficiency occurred because deforestation reduced root systems, diminishing soil cohesion, leading to soil erosion, and thus lowering the terrace's ability to trap sediment via filtration, rather than improving stabilization, therefore increasing land degradation.
