Question

Explanation:

Creep is slow, gradual soil movement with minimal immediate damage. Erosion is broad (not a mass movement type here). Slump is a slow, rotational slide of soil/rock. Landslides involve rapid, large-scale movement of rock, soil, and debris, often causing catastrophic damage to structures, landscapes, and loss of life, making them the most destructive.
