Sulfur Cycle

Sulfur cycle
Visual

Importance
  • Sulfur is part of an amino acid important to diet
  • Sulfur is needed for plants growth
Locks
  • Sulfur can be locked in plants and rocks
Human Impact
  • Burning of coal releases large amounts of sulfur dioxide which can mixed with water and make acid rain
  • Acid rain can also be cause by metal mining and road construction
Facts
  • Cycles in a gas and sedimentary cycle
  • It is needed by all living organisms
  • Cycle begins with the weathering of rocks
Process
  • The more important part of the sulfur cycle occurs in the ground, but sulfur can be found in the atmosphere too. 
  • When it is found in the atmosphere, sulfuric acid or sulfur dioxide. 
  • The sulfuric acid falls to the earth as acid rain. 
  • The amount of sulfate in the soil increases and causes problems for the environment.
  • Most of the sulfur on earth is an elemental sulfur, and some bacteria can can oxidize (combine with oxygen) the sulfur into sulfate. 
  • Sulfate can be used by plants to make proteins. 
  • When plants die, microorganisms turn the proteins into hydrogen oxide which can oxidize into elemental sulfur. 
  • Anerobic bacteria can change sulfate into hydrogen sulfide.
  • This can take place in waterlogged soil, this is where hydrogen sulfide can create high toxic levels. 
  • Sulfur can return to the atmosphere through volcanic eruptions

About Me

My name is Brianna, I like cats and Netflix. I also enjoy nice walks through the orchard and learning about science and stuff, which is a reason why I am taking this course. Plus I am going into the medical field so it is kinda a smart thing to take in high school. I am hoping to learn a lot of new things and get prepared for the AP test which, if I get a good enough score, will give me college credits.
