Which outcome occurred in the Waru Waru agricultural terrace system of the Andes due to diurnal temperature swings?

💡 Explanation

In Waru Waru systems, the raised beds and canals create a microclimate; because water has high thermal inertia, it releases heat during the night causing an increased local temperature. Therefore reduced frost damage results, rather than the other effects listed which would happen in terracing without this water mechanism.
