Answer:
The terms landslide or mudslide refer to the downward movement of large masses of rocks, soil, mud and organic debris. Areas with steep slopes, for example mountainous regions, are particularly susceptible to landslide hazards. Most landslides are caused by multiple factors that act together to destabilize the slope.
The primary cause of a landslide is the influence of gravity acting on weakened materials that make up a sloping area of land. While some landslides occur slowly over time (e.g., land movement on the order of a few meters/yards per month), the most destructive ones happen suddenly after a triggering event such as heavy rainfall or an earthquake.
