History

Which outcome accelerated soil loss when the pre-Columbian Anasazi over-farmed?

A)Arroyo formation increased dramatically
B)Chinampa systems fostered nutrient leaching
C)Terrace gradients induced waterlogging
D)Maize monoculture depleted potassium

💡 Explanation

Arroyos formed because over-farming depleted vegetation, therefore reducing soil cohesion. This initiated gully erosion, a positive feedback accelerating water flow and sediment transport into arroyos, rather than waterlogging on terraces or direct monoculture depletion.
