Which mechanism underpinned the use of terrace farming by the Incan civilization to enable maize cultivation?

💡 Explanation

When constructing agricultural terraces, the Inca utilized graded slopes to allow for the redistribution of water via gravity, thereby controlling erosion. Therefore, water control resulted from graded slopes rather than increasing humidity, cooling or reduced evaporation, because those depend on atmospheric or material properties.
