Question

How might the increase of volcanic eruptions affect Earth?

A. It might produce more ozone in the atmosphere


B. It might decrease temperature across Earth


C. It might increase the carbon dioxide in the atmosphere


D. It might cause the Earth’s surface to absorb more oxygen.

Answer 1

If enough ejecta (mainly ash) is sent into the upper atmosphere, the dust particles will block solar energy causing a decrease in temperature. This has happened in the past. Look for the year without summer caused by a volcanic eruption.
