When a volcano erupts, its actions are similar to which of the following events?

A. A food eroding the banks of a stream

B. A can of soda fling when it is opened

C. A tree root pushing up through the pavement

D. A building burning to the ground

Answer Explanation:

Both involve the release of pressure from a confined space. In the case of a volcano, pressure builds up beneath the Earth's surface, causing an eruption. Similarly, when a can of soda is opened, the release of pressure inside the can causes the soda to fizz and potentially spray out.

Therefore, the Correct Answer is B.
