Smelting: extracting metal from its ore by a process involving heating and melting
2. Burning coal
3.

The sulfur returns to earth's surface through acid deposition. ]]> 2016-09-11 22:19:05 UTC https://padlet.com/julisto/punc4ops0oy1/wish/122986584 Rocks and Minerals  julisto https://padlet.com/julisto/punc4ops0oy1/wish/122986815 Rocks and minerals release the sulfur they store through erosion. Anaerobic decomposers usually releases the sulfur back into the atmosphere.  ]]> 2016-09-11 22:22:43 UTC https://padlet.com/julisto/punc4ops0oy1/wish/122986815 Dimethyl sulfate julisto https://padlet.com/julisto/punc4ops0oy1/wish/122987567 Form of sulfur in which bacteria release into the atmosphere through anaerobic respiration. ]]> 2016-09-11 22:31:27 UTC https://padlet.com/julisto/punc4ops0oy1/wish/122987567
