Question

Quizplus · Accepted Answer

Mudflows can contain a wide range of particle sizes, from mud-sized particles to boulders. However, they are generally characterized by a high proportion of fine-grained material such as silt and clay, which gives them their characteristic fluid-like behavior. The water content can also vary widely, depending on factors such as the source of the flow and the amount of rainfall or snowmelt that has occurred.
