How did extensive terrace farming enable the Inca Empire to expand and sustain its territorial boundaries?

Option 1: Terrace farming helped the Inca Empire expand by providing surplus agricultural production, which allowed them to support a larger population and military forces.

Option 2: Terrace farming allowed the Inca Empire to maintain its boundaries by preventing soil erosion and landslides, which could threaten their agricultural resources and infrastructure.

Option 3: Extensive terrace farming helped the Inca Empire expand because it allowed them to cultivate crops at different altitudes, thereby increasing the variety of food available and supporting diverse populations in various regions.

Option 4: The Inca Empire used terrace farming to control water distribution, ensuring a stable and consistent water supply for their agricultural activities, which helped them maintain their boundaries in arid regions.

Extensive terrace farming helped the Inca Empire expand and sustain its territorial boundaries primarily by providing surplus agricultural production, supporting a larger population and military forces. Therefore, the correct option is Option 1: Terrace farming helped the Inca Empire expand by providing surplus agricultural production, which allowed them to support a larger population and military forces.

Explanation:

Terrace farming was a fundamental agricultural practice that significantly contributed to the Inca Empire's expansion and territorial sustainability. Through meticulous engineering and construction of terraced fields on steep slopes, the Inca people effectively maximized their agricultural output. This surplus in food production enabled the empire to support a larger population and maintain a formidable military force, which was crucial for expansion.

Terrace farming served as an agricultural innovation that prevented soil erosion and landslides, ensuring the preservation of vital farmland and infrastructure. By carefully designing and maintaining terraced structures, the Inca Empire mitigated the risks of soil degradation, retaining the integrity of their agricultural resources. This stability was vital in sustaining their boundaries and preventing potential setbacks that could arise from soil erosion or natural disasters.

Moreover, terrace farming allowed the Inca Empire to cultivate a diverse range of crops at various altitudes. This diverse agricultural output bolstered their ability to support diverse populations across different regions with varied climatic conditions.

By adapting their agricultural practices to different altitudes, they ensured a consistent food supply, further aiding in territorial expansion and sustaining their dominion. Therefore, the correct option is Option 1: Terrace farming helped the Inca Empire expand by providing surplus agricultural production, which allowed them to support a larger population and military forces.
