Question

During the eruption of Mount St. Helens on May 18, 1980, snow and glacial ice on the mountain melted and rushed down the Toutle River.

What is the name given to this specific type of mass wasting?

A. slump
B. creep
C. earthflow
D. rockslide
E. debris flow

Answer 1

E. debris flow

Step-by-step explanation:

• On May 1980 a major volcanic eruption occurred on Mount St. Helen's, located in Washington. Hot mix of lava and older rocks overtook the shape of an avalanche and the debris-laden mass of soil fragmented ricks and mudslides overtook the river systems and created liquefaction and high fluid pressure.
