While it might seem surprising, water vapor makes up a significant portion of volcanic gases, often more than 90%. Other common gases include:
* Carbon dioxide (CO2): A major greenhouse gas, it contributes significantly to the Earth's atmosphere.
* Sulfur dioxide (SO2): A major air pollutant, it can form acid rain and contribute to respiratory problems.
* Hydrogen sulfide (H2S): A highly toxic gas with a rotten egg smell.
* Hydrogen chloride (HCl): A corrosive gas that can contribute to acid rain.
* Hydrogen fluoride (HF): A highly corrosive gas that can be dangerous to human health.
It's important to note that the exact composition of volcanic gases can vary depending on the volcano, the type of eruption, and the surrounding environment.
