Which outcome occurs when the Inca irrigation system's andenes terraces experience extreme rainfall followed by rapid freezing?

💡 Explanation

Crop yield variability increases due to freeze-thaw weathering, breaking terrace walls destabilizing the overall structure. Because differential soil expansion leads to erosion, therefore the land's support changes rather than simply changing hydraulic parameters; this leads to unreliable harvests.

• Which outcome threatens Inca terrace wall stability following intense rainfall?
• Which consequence resulted from carbon levels exceeding threshold in early iron smelting?
• Which outcome occurred in pre-Columbian terraced agriculture when erosion exceeded replenishment?
• Which structural weakness commonly arose during the transition from wooden to iron shipbuilding during the 19th century era?
• Which constraint primarily limited the yield of maize crops grown in Aztec chinampas?
• Which benefit occurred due to terrace construction combined with sophisticated irrigation in Inca maize cultivation?
