Why did the incas build terraces A to improve travel and communication through the empire B to allow them to build homes on the sides of mountains C to make it easier to climb high mountains D to increase the amount of fertile farmland

1 answer

The primary reason the Incas built terraces was D to increase the amount of fertile farmland. The mountainous terrain of the Andes made it challenging to cultivate crops, so the Incas created terraces to create flat surfaces for agriculture and to improve irrigation. This innovative agricultural technique allowed them to maximize farmable land and effectively manage water resources in a challenging environment.
