Q: What's it called when there's a sudden flow of mud?


Read this paragraph and choose the correct option from the provided answers:

A mudflow is the sudden flow of mud down a slope because of gravity. Mudflows occur where the soil is mostly clay. Like landslides, mudflows usually occur when the soil is wet.
