The Andes mountains are rugged and steep, so the Inca had to adapt to the challenging terrain in order to build their vast empire. They developed sophisticated agricultural techniques such as terrace farming, irrigation systems, and crop rotation to maximize food production in the mountainous environment. They also built an extensive network of roads and bridges to connect their empire and facilitate communication and trade. Additionally, the Inca developed a system of communication using runners called "chaskis" to quickly relay messages across the mountainous terrain. Overall, the Inca adapted to the unique challenges of the Andes mountains through innovation and ingenuity.
