Which critical challenge did terrace construction directly address for pre-Columbian highland agriculture?

💡 Explanation

Terraces were built to create level platforms, thereby greatly increasing the surface area for cultivation. Because the slope is broken up into smaller, less steep gradients, soil erosion from heavy rains is minimized via decreased runoff velocity, rather than optimizing nutrient absorption efficiency.

• Which error increases when a historical marine sextant's horizon mirror develops significant parallax?
• Which consequence results when archaeologists unearth bronze tools after extended burial in saline soil?
• Which mechanical risk increased for builders scaling Inca dry-stone walls?
• Which consequence results from 'dry stone' masonry lacking mortar?
