Answer :
Final answer:
The Inca used terracing to farm on hills and mountainsides, creating flat platforms and preventing soil erosion.
Explanation:
The farming method that helped the Inca farm on hills and mountainsides is terracing. Terracing involved creating flat platforms, or steps, on the mountain slopes, which helped to prevent soil erosion and enabled the Inca to cultivate crops. By building stone retaining walls, the Inca were able to create flat areas for cultivating crops such as corn, potatoes, and quinoa.
One example of terracing by the Inca can be seen in the agricultural site of Moray, located in present-day Peru. The circular terraces in Moray were used to experiment with different crops and growing conditions. This technique allowed the Inca to adapt to the challenging mountainous terrain and maximize agricultural productivity.
