Detailed explanation-1: -By far the most abundant volcanic gas is water vapor, which is harmless. However, significant amounts of carbon dioxide, sulfur dioxide, hydrogen sulfide and hydrogen halides can also be emitted from volcanoes.
Detailed explanation-2: -Ninety-nine percent of the gas molecules emitted during a volcanic eruption are water vapor (H2O), carbon dioxide (CO2), and sulfur dioxide (SO2). The remaining one percent is comprised of small amounts of hydrogen sulfide, carbon monoxide, hydrogen chloride, hydrogen fluoride, and other minor gas species.
Detailed explanation-3: -The most common volcanic gas is water vapor, followed by carbon dioxide and sulfur dioxide. Sulfur dioxide can cause breathing problems in both healthy people and people with asthma and other respiratory problems. Other volcanic gases include hydrogen chloride, carbon monoxide, and hydrogen fluoride.
Detailed explanation-4: -Oxygen is actually the second most abundant element in the Earth, right after iron. While most of the oxygen was in rocks, some oxygen atoms formed water molecules (H2O) and carbon dioxide (CO2). These molecules came out of volcanoes as gases and formed the ocean and the atmosphere.
