What is the primary effect of volcanic activity on an area's climate?

• The release of carbon dioxide cools the area around the volcano.

• The release of sulfur dioxide results in the creation of aerosols that block sunlight from reaching areas around the volcano.

• The release of ash results in a cooler environment around the base of the volcano.

What is the greenhouse effect?

• The warming of a planet due to trapped radiation.
• The cooling of Earth due to air pollution.
• The heating of a solid, such as a rock.
