Which purpose did extensive terracing serve within the agricultural practices of the Inca civilization?

💡 Explanation

When constructing agricultural terraces on steep Andean slopes, the level platforms slowed water flow and increased infiltration rate in the soil, reducing losses. Thus, this design minimized runoff and erosion rather than using geothermal heat, creating reservoirs, or preventing frost damage which do not explain this design benefit.
