History

Which consequence directly followed widespread water damage due to inadequate implementation of stepped terracing in ancient Inca highlands?

A)Unstable terrain; soil erosion
B)Increased crop biodiversity index
C)Greater nitrogen fixation efficiency
D)Lower chance crop-seed germination

💡 Explanation

The primary outcome is significant soil erosion because without proper drainage (terrace FAILURE mechanism), increased water saturation destabilizes the underlying soil structure, therefore the risk of landslides rises rather than nitrogen fixation within topsoil layers.
