Q: What is released during a volcanic eruption that causes a volcanic winter?
A: Ash and sulfur dioxide are released during a volcanic eruption that causes a volcanic winter.
Q: What do sulfur dioxide and ash form during a volcanic eruption?
A: Sulfur dioxide and ash form aerosols of sulfuric acid during a volcanic eruption.
Q: What happens to the sunlight when sulfuric acid aerosols reach the stratosphere?
A: When sulfuric acid aerosols reach the stratosphere more sunlight is reflected, and some is absorbed by the stratosphere.
Q: What is the effect of the reactions that occur with sulfuric acid aerosols in the stratosphere?
A: The reactions that occur with sulfuric acid aerosols in the stratosphere heat up the stratosphere, but lead to a drop in temperature on the ground.
Q: What are some examples of huge flood basalt provinces caused by volcanism?
A: The Siberian Traps, Emeishan Traps, and Deccan Traps are examples of huge flood basalt provinces caused by volcanism.
Q: What is nuclear winter?
A: Nuclear winter is a theory of similar effects which might be caused by a large-scale nuclear war.
