Volcanic eruptions can influence the climate both by cooling as well as by warming the atmosphere.

Question

Quizplus · Accepted Answer

When a volcano erupts, it shoots out a large amount of ash and sulfur dioxide into the atmosphere. This ash can reflect incoming solar radiation, which can lead to cooling of the Earth's surface. On the other hand, sulfur dioxide can combine with water vapor in the atmosphere to form tiny droplets of sulfuric acid, which can absorb and scatter solar radiation. This can lead to warming of the atmosphere. Therefore, volcanic eruptions can have a cooling or warming effect on the climate, depending on the amount and composition of the ejected materials.
