Answer :
Final answer:
The Incas utilized advanced agricultural techniques such as terracing, irrigation, and crop rotation to grow crops in the challenging mountainous terrain of the Andes. These methods helped them to create arable land, manage water resources, and maintain soil fertility. Their innovations allowed for successful farming and supported their civilization's growth.
Explanation:
How the Incas Grew Crops in the Mountains
The Inca civilization, which thrived in the Andes mountains of South America, developed a range of innovative agricultural techniques to cultivate crops in challenging mountainous terrain. Here are some key methods they employed:
- Terracing: The Incas constructed terraces on the steep slopes of the mountains. These terraces helped to create flat areas for planting crops and reduced soil erosion by preventing the runoff of water and soil.
- Irrigation: They managed complex irrigation systems that diverted water from rivers to their fields. This ensured a reliable water supply for crops, which was crucial for farming in an environment with unpredictable rainfall.
- Crop rotation: The Incas practiced crop rotation and planted a mix of crops, including potatoes, maize, quinoa, and more. This method maintained soil fertility and reduced pests and diseases.
Through these advanced agricultural techniques, the Incas were able to maximize food production in the harsh environment of the Andes, supporting a large population and a complex society.
