mudslide
Britishnoun
Explanation
When dirt, rocks, and water flow down the side of a mountain, it's called a mudslide. Heavy rain and melting snow can both cause mudslides. Another name for a mudslide is a debris flow. It's a fast-moving type of landslide that's made at least partly of mud, which gives the phenomenon its name. Mudslides often happen after natural disasters (like earthquakes), and hillsides that have been burned by wildfires or developed by people are more vulnerable. The effects of mudslides include impassable roads, broken pipes and cables that cause water and power outages, and even homes buried under mud.
