Volcanic Gases and Their Effects

The report discusses gases trapped in magma below the Earth's surface as the driving force of volcanic eruptions. Types of gases, such as sulfur dioxide and carbon dioxide, and their potential effects are described. A comparison of volcanic gas composition in three different volcano types is also given.
