Sulfur Dioxide Acid Rain
318 wordsAcid Rain is, rain that is acidic (naturally). There is a pH level scale which tells if something is acidic or not. Due to certain chemicals in the rain it has a pH level of around 5. 0, and sometimes even 4. 0 (around volcanoes activity). The term acid rain is now used for rain with a pH below 5. Acid rain is caused when gases, generally like sulfur dioxide (SO 2), dissolves into water to form sulfuric acid. The rest comes from different oxides of nitrogen (mainly NO 2 and NO 3). The chemical r...

Hydrothermal Vents Hydrogen Sulfide
580 wordsHydrothermal Vents are considered by scientists to be very unique and complex communities of organisms. The reason for this is due to the fact that unlike most other organisms, Hydrothermal Vents are not powered by the sun s energy. Most organisms on the Earth+s surface depend on plants to produce nutrients from sunlight. This process is called photosynthesis. These communities are unique in that they depend on a different food-making process other than photosynthesis. Bacteria at the vents make...
