Question

These diagrams are topographic maps of Mount St. Helens in Washington state.

They were made before and after the volcano erupted in 1980. What do these two
maps tell us about the eruption?

A The eruption melted a glacier and caused massive flooding.

B The eruption blew out the north wall of the volcano's cone.

C The eruption destroyed most of the surrounding forest.

D The eruption did not change the shape of the volcano.

Answer 1

Answer: The correct answer is B The eruption blew out the north wall of the volcano's cone.

Step-by-step explanation:

In the map displayed below, the contours lines are more dense after the eruption and the north wall is no longer present. This likely was also the path of the lava flows following the erruption.
