Which process increases due to water saturation in ancient Inca terraces?

💡 Explanation

Increased water saturation causes slope instability because pore pressure increases the effective stress between soil particles, therefore reducing shear strength making landslides more likely, rather than root strength increasing or albedo decreasing after heavy rains.
