← HistoryWhich consequence resulted when ancient terrace construction exceeded friction limits?
A)Accelerated topsoil erosion downhill✓
B)Decreased overall light refraction
C)Increased downstream chemical sedimentation
D)Induced thermal cantilever fracturing
💡 Explanation
Accelerated topsoil erosion downhill arose due to exceeding terrace friction limits; the shear stress overcomes soil cohesion, creating landslides. This happens because gravitation pull outweighs terrace friction rather than stable soil structure, leading to significant material loss downhill.
