  2. Flows: A mixture of water, rock and weathered material. They move very quickly. Large flows can bury an entire village. Small flows can block roads.
  3. Slide: A slide happens when section of soil or rock suddenly gives way and moves down a slope. The material moves as a single mass along a slippery zone.
  4. Creep: It is a very slow mass movement that goes on for years or even centuries.
