Which outcome accelerated erosion when terrace farming lacked proper drainage during the Inca Empire?

💡 Explanation

When terrace drainage was inadequate, hydrostatic pressure built up behind terrace walls because accumulated water increased the lateral force, leading to wall collapse and accelerated erosion. Therefore destabilization resulted, rather than runoff, salts, or compaction which require different geochemical mechanisms or soil properties.
