what is the principal difference between a debris flow and a mudflow?
o a debris flow contains pyroclastic debris, but a mudflow does not
the shape of the path taken by the moving mass
the size of the material that comprises the moving mass
a debris flow contains abundant water, but a mudflow is dry

Explanation:

Debris flow and mudflow are both types of mass - wasting processes. Debris flow consists of larger - sized materials like boulders, rocks, and soil along with water. Mudflow, on the other hand, is mainly composed of fine - grained materials (silt, clay, sand) along with water. The key difference lies in the size of the material that makes up the moving mass. Pyroclastic debris is related to volcanic activity and not the general difference between debris flow and mudflow. The shape of the path is not the principal difference. Both debris flow and mudflow contain water (mudflow has a higher water - to - sediment ratio in some cases, but the dryness claim is incorrect).

Answer:

the size of the material that comprises the moving mass
