Which risk increases when ancient Andean terraces experience deforestation?

💡 Explanation

Deforestation reduces root systems which formerly stabilized the terrace, leading to increased erosion through surface runoff; soil nutrient retention decreases because the vegetation can no longer anchor and recycle essential elements, therefore causing land infertility rather than structural failure.
