Answer to Question 1

Answer: Volcanic eruptions eject large volumes of debris and gases into the atmosphere through an eruption column. The smaller, volcanic ash particles reflect sunlight back into space thus lowering the mean temperature of the atmosphere. Aerosols will also have the same impact on mean atmospheric temperatures. Volcanic ash can also clog airplane engines, impairing travel. Volcanic gases such as sulfur dioxide can react with moisture in human lungs to produce sulfuric acid, which is a deadly toxin.
