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

A)Increased landslide vulnerability occurs downslope
B)Accelerated weathering increases material failure
C)Decreased crop yield diminishes terrace value
D)Amplified erosion forms depositional landforms

💡 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.
