What geographic feature limited the eastward expansion of the Inca Empire? Atlantic Ocean Amazon River Andes Mountains Pacific Ocean

The Andes Mountains were a formidable geographic barrier for the Inca Empire, stretching along the western edge of South America. This impressive mountain range not only posed challenges for expansion due to its steep terrain and high altitudes, but it also affected agricultural practices, transportation, and communication within the empire. The Incas brilliantly adapted by developing extensive road systems and terrace farming, allowing them to thrive despite these natural obstacles. In addition to the Andes, the Amazon River also served as another significant limitation to eastward expansion. The dense jungles and difficult terrain of the Amazon Basin created a challenging environment, full of natural obstacles and a different ecosystem compared to the highlands of the Andes. This made it tough for the Incas to project their influence and establish control in the lush, tropical territories to the east.
