Which outcome resulted from ancient terracing during heavy rainfall?

💡 Explanation

Terracing slowed erosion because gradient reduction decreased the kinetic energy of overland water flow, therefore lessening soil detachment and transport, rather than inducing hydrostatic pressure or increasing erosion like on steeper slopes.

• During the medieval era, which risk increased in densely populated Chinese cities adopting gunpowder weapons against defensive walls?
• Which destabilizing outcome results when Inca terracing lacks sufficient hydrostatic pressure release?
• Which mechanism allowed medieval astrolabes to indirectly determine the height of distant objects like towers?
• Which limit constrained the effectiveness of Inca quipu for decentralized recordkeeping?
• Which error arises when a 18th-century navigator uses a sextant without correcting for index error?
• Which mechanical risk amplified the collapse-hazard when windstorms impacted medieval rope bridges?
