← HistoryWithin ancient Mesopotamian agriculture, which environmental hazard increases due to over-irrigation in sloped levee systems?
A)Increased soil salinity✓
B)Declining crop pollination
C)Catastrophic levee collapses
D)Decreased average soil temperature
💡 Explanation
Soil salinization increases due to capillary action drawing saltwater upward with the water table via evaporation, facilitated by the capillary action mechanism. This occurs especially in arid climates because evaporation deposits salts at the surface, rather than flowing away; therefore it accumulates.
