Which risk increased in early terrace farming, if terraces lacked sufficient drainage?

💡 Explanation

Increased water saturation elevated pore pressure, reducing soil shear strength; therefore, slope failure risk increased because effective soil compaction reduces stability, rather than sunlight exposure dominating crop health or any external impact.

• Which consequence decreased the utility of silk as imperial gifts during the medieval Byzantine-Arab wars?
• Which mechanism allowed early suspension bridges to span longer distances than arch bridges?
• When reconstructing incomplete astrolabes, which consequence arises from incorrectly determining the original plate scale factor through algebraic estimation?
