← HistoryWhich outcome occurs when pre-Columbian terrace construction fails?
A)Topsoil erosion increases dramatically downgrade✓
B)Water flow redirection upstream intensifies
C)Crop yield doubles unexpectedly
D)Soil nutrient concentration shifts laterally
💡 Explanation
Topsoil erosion accelerates due to the hillsides exposure, induced by terracing failure. The mechanism is surface runoff intensifying because loss of terrace structure; therefore soil loss happens rather than enhanced fertility or flow redirection, which are caused by other hydrologic impacts.
