Question 1

Correct Answer:

Verified

Volcanic ash will collect on rooftops and present other hazards to travel and people in both locations. The danger to a home will depend on the ash piling up on the roof, creating a danger of collapse. The danger is greater if the ash is wet. Either volcano can produce rain as a side effect of the eruption. Mt. Rainier is in an area that has a lot more snow, so this danger is a larger concern there.
