The Sulfur Cycle Biology for Majors II

Atmospheric sulfur is found in the form of sulfur dioxide SO 2 and as rain falls through the atmosphere sulfur is dissolved in the form of weak sulfuric acid H 2 SO 4 Sulfur can also fall directly from the atmosphere in a process called fallout Also the weathering of sulfur-containing rocks releases sulfur into the soil...
