Which mechanical process most directly improves agricultural yield when terrace walls experience outward creep?

💡 Explanation

Terrace creep compacts soil behind walls; therefore a reduction in concentrated soil overburden improves yield because it decreases instability due to plastic deformation, rather than altering sunlight or nutrients.
