Answer

Rock avalanche Explanation 1. Identify the types of mass movement Rock avalanche, lahar, debris flow, and slump are all types of mass movements with varying speeds. 2. Determine the speed of each type Rock avalanches are extremely rapid, often reaching speeds over 100 km/h. Lahars can also be fast but typically slower than rock avalanches. Debris flows are rapid but not as fast as rock avalanches. Slumps are slow compared to the others.
