History

Which long-term ecosystem effect occurred when the Inca abandoned terraced farming?

A)Topsoil erosion accelerated drastically downstream
B)Local amphibian populations experienced overgrowth
C)Predator populations collapsed unpredictably upstream
D)Crop specialization drove greater food security

💡 Explanation

Accelerated topsoil erosion occurred upon abandonment because gravitational potential drives soil particles down the terrace steps in the absence of root cohesion slowing the runoff. Increased erosion occurred, therefore, rather than stability, because regular terracing prevented substantial soil loss.
