Which of the best explains one of the ways in which Inca used astronomy to manipulate their environment?
One of the ways in which the Inca used astronomy to manipulate their environment was through their agricultural practices. They observed and studied the movement of celestial bodies, particularly the sun, to determine the appropriate timing for planting and harvesting crops.
The Inca developed an intricate agricultural system known as "Waru Waru," which involved constructing raised bed platforms separated by a network of canals and trenches. They aligned these beds and canals with specific celestial events, such as the rising and setting of the sun during solstices and equinoxes.
By aligning their agricultural infrastructure with astronomical events, the Inca maximized their crop yields. The sun's rays would hit the crops more directly during crucial stages of growth, enhancing photosynthesis and increasing productivity. The canals and trenches helped control water distribution and prevent flooding or droughts, ensuring optimal conditions for the crops.
Additionally, the Inca used astronomical observations to predict changes in weather patterns and seasonal shifts. They had an advanced understanding of celestial cycles, allowing them to anticipate changes in the pattern of rainfall, temperature, and growing seasons. This knowledge enabled the Inca to adapt their agricultural practices and make informed decisions about crop selection and cultivation techniques.
Overall, through their extensive study of astronomy, the Inca were able to manipulate their environment by creating an efficient and sustainable agricultural system, ensuring food security for their empire.
