Which issue increased when ancient Incas extended terraced fields?

💡 Explanation

Increased field area means steeper/taller retaining walls of stone, meaning more Hydraulic head. Increased water pressure promotes Sapping, causing structural failure and material transport because pore water pressure supports particles; therefore downstream gets excess deposition, rather than even nutrient diffusion.
