Answer :
Final answer:
Terrace farming by the Incas was a significant adaptation to their physical geography, allowing them to cultivate crops on steep mountainous terrain. This agricultural method helped manage water flow and retain soil, enhancing food production. So, the correct answer is D: physical geography.
Explanation:
The Use of Terrace Farming by the Incas
Terrace farming was a crucial agricultural technique developed by the Incas as an adaptation to their unique physical geography. The Andes Mountains presented challenges such as steep slopes and varying elevations, making traditional farming difficult. By constructing terraces, the Incas were able to create flat areas for planting, which helped manage water run-off and soil erosion.
This method allowed them to cultivate crops effectively in a rugged landscape, optimizing agricultural production in a region with limited arable land. These terraces also facilitated irrigation and improved microclimates for growing crops like potatoes and maize, vital to the Incas' diet.
Thus, the correct answer to the question is D: physical geography, as terrace farming is a direct response to the challenges posed by the natural landscape of the Andes.
