Which consequence results when unsupported terrace construction exceeds cohesive soil limits?

💡 Explanation

Increased landslide vulnerability results because exceeding soil’s cohesive strength triggers slope failure through rotational SLUMPING, displacing the terrace downwards. This concentrates mass, exacerbating shear stress rather than distributing load; therefore downslope instability is amplified, not mitigated.
