Why do volcanic eruptions cause cooling for the weeks/months following the eruption?
A) increased sulfur in the atmosphere reflect energy from the sun
B) volcanic ash acts as a shield to block the sun's energy from reaching earth
C) carbon dioxide is emitted during the eruption
D) both A and B

Question

Quizplus · Accepted Answer

Volcanic eruptions release sulfur dioxide gas and other aerosols into the atmosphere. These particles reflect and scatter some of the incoming solar radiation back to space, which causes cooling. Additionally, volcanic ash can block sunlight from reaching the Earth's surface which can also result in decreased temperatures. Therefore, both options A and B are correct. Carbon dioxide emissions from volcanic eruptions are not significant enough to cause cooling as it is a greenhouse gas that traps heat in the atmosphere.
