Which effect results when ancient Andean terrace retaining walls experience increased hydrostatic pressure from saturated soil?

💡 Explanation

When walls experience hydrostatic pressure, pore water pressure accumulates and reduces effective stress, initiating soil failure along a continuous rupture surface creating terrace slippage. Therefore, terrace slippage results, rather than crop failure, albedo increase, or reduced evapotranspiration which require different physical causes.
