Compare rapid mass movements with slow mass movements?

Rapid mass movements occur suddenly and can travel at high speeds due to factors like steep slopes or heavy rainfall, leading to landslides, rockfalls, or avalanches. Slow mass movements, such as soil creep or solifluction, involve gradual downslope movement of material over an extended period, often influenced by factors like gravity and water infiltration. While rapid mass movements pose immediate risks and can cause significant damage, slow mass movements are generally more subtle but can still contribute to landscape changes over time.
