Although carbon dioxide is released during a volcanic eruption, another gas plays a much bigger role in climate change, and rather than warming the climate it to cool the climate. use the model to explain how this cooling effect takes place.

a) volcanic ash or dust released into the atmosphere during an eruption stay in the stratosphere for months, blocking sunlight and causing cooling over large areas of the earth.

b) the by-products of combustion, water vapor and carbon dioxide, remain in the atmosphere. the result is a greater build-up than normal of greenhouse gases, resulting in warming of the earth's climate.

c) aerosol gases released by the eruption move into the upper atmosphere. these gases disrupt the ozone, widening the hole that already exists. as a result, there is more incoming solar radiation, causing the earth to become warmer.

d) sulfur dioxide emitted into the stratosphere combines with water to form sulfuric acid aerosols. this makes a haze of tiny droplets in the stratosphere that reflects incoming solar radiation, causing cooling of the earth’s surface.
