How do volcanic eruptions affect Earth's temperature?
What will be an ideal response?
Explosive volcanic eruptions eject large volumes of volcanic ash and sulfurous aerosols into the atmosphere, both of which block or absorb incoming solar radiation to cause cooling. The aerosol effect is the greater one because the aerosols can be distributed throughout the atmosphere and remain there for many years; most of the ash particles settle out within days or weeks and are only present in areas downwind of the volcano.
