USA HISTORY

Detailed explanation-1: -The Inca lived in the Andes Mountains in South America. Their range stretched from southern Chile through Argentina, Bolivia, Peru, and Ecuador and into southern Colombia. The Inca were very warlike and often attacked their neighbors to take their land.

Detailed explanation-2: -And between 1150 and 1300, the Inca around Cusco began to capitalize on a major warming trend in the Andes. As temperatures climbed, Inca farmers moved up the slopes by 244 to 305 meters (800 to 1, 000 feet), building tiers of agricultural terraces, irrigating their fields, and reaping record corn harvests.

Detailed explanation-3: -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-4: -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.
