← HistoryWhich outcome results downstream when terrace erosion occurs?
A)Increased sedimentation in irrigation canals✓
B)Enhanced fertilizer dispersion upslope farms
C)Greater biodiversity within terrace ecosystem
D)Increased carbon sequestration in topsoil
💡 Explanation
Increased sedimentation results from terrace erosion due to increased runoff; the entrained soil deposits silt and clay downstream. Because `sediment transport` overwhelmed flow capacity, deposition occurred, leading to plugged irrigation canals, therefore disrupting agricultural capacity rather than enhancing fertilization.
