Question

Quizplus · Accepted Answer

The grain size of the moving mass is the principle difference between a debris flow and a mudflow. A debris flow consists of a mixture of soil, rock fragments, and water with a coarse texture, while a mudflow consists of fine-grained particles and water that results in a smooth texture. The shape of the path taken by the moving mass could be the same or similar for both debris flow and mudflow depending on the terrain, and both types of flows could contain water. Debris flow could contain pyroclastic debris, but this is not a principle difference between the two types of flows.
