Volcanic eruptions send sulfur dioxide, tons ofashes, and soot into the air which mixes with water vapor to form acid rain. Dirt particles can also becarried to the atmosphere during wind erosion. This happens in areas with less vegetation where soilcannot be held together.Bacteria that feed on decaying organic matter like plants or animals produce methane and carbondioxide, which are released into the atmosphere. Earth's crust is composed is composed of a radioactiveelement called Uranium. Uranium turns into Radium once it decays afterward forming Radon. Radon is agas that combines with air through evaporation. Human activities or anthropogenic sources also cause airpollution. These activities mostly involve burning of fuel. Stationary sources include factories and powerplants. Mobile sources, on the other hand, are motor vehicles, aircraft, and water vessels.There are still other human-based causes of air pollution.
