GPT-4o mini
Both a and b contribute to a "volcanic winter."
a) Sulfur dioxide reacting in the atmosphere can lead to the formation of sulfate aerosols, which reflect sunlight and can cool the Earth's surface.
b) Volcanic ash can block out sunlight, also leading to cooling effects on the climate.
c) While molten rock (lava) can cause destruction and alter landscapes, it does not contribute to the cooling effect associated with a "volcanic winter" in the same way that sulfur dioxide and ash do.
So, the correct answers are a and b.
a) Sulfur dioxide reacting in the atmosphere can lead to the formation of sulfate aerosols, which reflect sunlight and can cool the Earth's surface.
