Question

Why might a major volcanic eruption lead to cooler temperatures over a lager area around the volcano?

Answer 1

a major volcanic eruption can lead to cooler temperatures, because:

The smoke emitted from the volcano would cover the sky in the area, which would become dark, and is impenetrable from light. When there isn't light from the sun, the heat also cannot go through, making the temperature drop after a volcanic eruption

Answer 2

Volcanoes can impact climate change. During major explosive eruptions huge amounts of volcanic gas, aerosol droplets, and ash are injected into the stratosphere. But volcanic gases like sulfur dioxide can cause global cooling, while volcanic carbon dioxide, a greenhouse gas, has the potential to promote global warming.
