← HistoryWhat advantage was directly gained by the Inca by aligning agricultural terraces parallel to the direction of prevailing winds?
A)Increased radiative surface cooling✓
B)Enhanced evaporative moisture loss
C)Reduced mechanical erosion hazard
D)Greater nutrient mixing uniformity
💡 Explanation
Increased altitude and diurnal oscillation on terraces cause damage, while airflow enhances convective passive radiative cooling because the increased surface area due to terracing promotes heat dissipation. Therefore, option A is correct, rather than moisture loss, which can lead to crop failure.
