Which consequence results when terraced hillsides lack sufficient drainage channels?

💡 Explanation

Landslides occur because increased water saturation within the terraces causes increased pore pressure, therefore reducing soil shear strength until slope failure occurs, rather than offering stability under wet conditions.
