Avalanches are most likely to occur on slopes between 30^circ and 45^circ (True or False) 10. Human activities like building on steep slopes, can contribute to the likelihood of mass movements. (True or False)

Answer 1

1. The force responsible for mass movements is gravity.2. Water increases the risk of mass movement by saturating the soil, increasing its weight, and reducing friction between grains.3. Creep is the slow, steady downhill movement of loose, weathered earth materials.4. A lahar is a volcanic mudflow that occurs when melted snow mixes with ash after an eruption.5. The crescent-shaped scars on slopes are typically left by landslides, a type of movement along a curved surface.6. Rockfalls commonly occur on steep cliffs and produce cone-shaped piles of debris called talus.7. To reduce the risks of mass movements, steep slopes can be stabilized using materials such as geogrids or retaining walls.8. Creep is a slow-moving type of mass movement that causes gradual changes to slopes. (True)9. Avalanches are most likely to occur on slopes between 30° and 45°. (True)10. Human activities like building on steep slopes can contribute to the likelihood of mass movements. (True)
