Which type of mass wasting event, common on steep mountain slopes in Himachal Pradesh during heavy monsoon downpours, involves the rapid downslope flow of saturated soil, rock, and debris behaving like a muddy liquid slurry?

💡 Solution & Explanation

Debris flows are fast-moving, destructive types of mass movement where loose soil and rock mixed with large amounts of water rush down mountain slopes, frequently triggered by cloudbursts or intense rainfall in Himalayan regions. Rockfalls involve free-falling rock fragments from sheer cliffs. Understanding slope failure mechanisms helps in designing effective infrastructure protection along mountain highways.
