Which risk increases when pre-Columbian terracing lacks sufficient drainage?

💡 Explanation

Accelerated structural creep deformation becomes a risk because hydrostatic pressure increases pore water pressure, weakening soil cohesion via effective stress reduction; therefore deformation increases rather than enhanced plant growth which requires aeration.
