Particulates of these salts can enter the atmosphere from sea spray, dust storms, and forest fires. Sulfur also enters the atmosphere as hydrogen sulfide and sulfur dioxide, which are released from decaying organic matter and volcanic activity. Dimethyl sulfide is another form of sulfur present in the atmosphere; it comes from marine algae. Reactions in the atmosphere produce sulfur trioxide gas and sulfuric acid, which fall to the earth in acid rain. Sulfate ions can be converted to sulfide ions in soil, which can then form metallic sulfides and be deposited as rock or metal ores, and the cycle begins again.]]> 2018-09-10 14:47:52 UTC https://padlet.com/ejtrunne/78s6bshv7g2x/wish/279441210 arscrugg https://padlet.com/ejtrunne/78s6bshv7g2x/wish/279444806 2018-09-10 14:53:17 UTC https://padlet.com/ejtrunne/78s6bshv7g2x/wish/279444806 andrmat https://padlet.com/ejtrunne/78s6bshv7g2x/wish/279906926 Sulfur begins it's biotic cycle in the ground. It is absorbed along with other nutrients by plants and used by them to make proteins. Straight from the ground, bacteria convert sulfur from it's solid state to a gaseous state. The gas rises
and enters the atmosphere. From the atmosphere, it rains down as acid rain to reenter the ground and solidify. Humans burn sulfur containing coal and oil, and use many sulfur based compounds in their everyday life. This results in more sulfur being added to the atmospheric and geologic components of the sulfur cycle. In the long run, humans could alter the natural rate of this cycle.]]> 2018-09-11 15:04:25 UTC https://padlet.com/ejtrunne/78s6bshv7g2x/wish/279906926 ejtrunne https://padlet.com/ejtrunne/78s6bshv7g2x/wish/279909650 2018-09-11 15:08:24 UTC https://padlet.com/ejtrunne/78s6bshv7g2x/wish/279909650 andrmat https://padlet.com/ejtrunne/78s6bshv7g2x/wish/280294734 2018-09-12 12:14:14 UTC https://padlet.com/ejtrunne/78s6bshv7g2x/wish/280294734 andrmat https://padlet.com/ejtrunne/78s6bshv7g2x/wish/280295222 2018-09-12 12:15:32 UTC https://padlet.com/ejtrunne/78s6bshv7g2x/wish/280295222 andrmat https://padlet.com/ejtrunne/78s6bshv7g2x/wish/280296592 2018-09-12 12:19:08 UTC https://padlet.com/ejtrunne/78s6bshv7g2x/wish/280296592
