Question

what happened during the eruption of mt. st. helens? check all that apply. the west side of the mountain blew up and spread debris. many people who documented the event lost their lives. a glacier began to move down the side of the mountain. a massive cloud of smoke and ash rose into the air. the explosion moved too quickly for people to outrun it. ash traveled as fast as 1,000 miles per hour.

Explanation:

During the 1980 eruption of Mt. St. Helens, the north - side of the mountain blew up (not the west side). Many people documenting the event, like volcanologist David Johnston, lost their lives. The eruption caused a massive cloud of smoke and ash to rise into the air. The explosion was extremely fast - moving and difficult for people to outrun. There is no evidence of a glacier starting to move down the side of the mountain during the eruption, and ash did not travel at 1,000 miles per hour.

Answer:

B. Many people who documented the event lost their lives.
D. A massive cloud of smoke and ash rose into the air.
E. The explosion moved too quickly for people to outrun it.
