USA HISTORY

Detailed explanation-1: -Although the empire was huge, it can be easily divided into three geographical regions: mountains, jungle, and desert. What three geographic features dominated the Inca empire? Andes Mountains: The Andes Mountains, home of the Inca civilization, ran north to south. The mountains dominated Inca society.

Detailed explanation-2: -The empire was long and narrow because the great Andes Mountains blocked settlement further inland into the South American continent. The cities of the Incas and the tribes they conquered were built on the flat coastal plain or were located in the mountainous area.

Detailed explanation-3: -The territory covered much of modern-day Peru, Ecuador, and part of Colombia. The landscape featured large open valleys, deep canyons, high plateaus, coastal valleys, and deserts, giving road builders many challenges.

Detailed explanation-4: -The higher temperatures, starting around 1150, ended thousands of years of cold aridity, and enabled Incan farmers to build mountainside terraces for growing crops at altitudes previously too cold to support agriculture.

Detailed explanation-5: -The Incas developed techniques to overcome the difficult territory of the Andes: on steep slopes they built stone steps, while in desert areas near the coast they built low walls to keep the sand from drifting over the road.
