How does carbon dioxide enter the atmosphere?

Answer:
Carbon dioxide (CO2) is released from various sources such as living beings, industries, automobiles, burning of fossil fuels, etc.
  • Respiration from plants and animals.
  • Decay of plant and animal matter. This converts to carbon dioxide in the presence of oxygen, or into methane if there is no oxygen.
  • Burning of any organic material oxidizes the carbon to produce carbon dioxide.
    • Burning fossil fuels releases CO2 that has been stored for millions of years.
    • Burning biofuels releases CO2 that has been stored for only a few years, or less.
  • Production of cement. When limestone is heated to produce lime, CO2 is released.
  • As the oceans become warmer, CO2 is released from the surface.
  • Volcanoes emit water vapor, CO2 and sulfur dioxide. Silicate weathering is a process that removes CO2 and the two processes, the chemical reverse of each other, cancel each other out.



Carbon dioxide is manufactured mainly from seven processes:
  1. As a by-product in ammonia and hydrogen plants, where methane is converted to CO2;
  2. from combustion of wood and fossil fuels;
  3. as a by-product of fermentation of sugar in the brewing of beer, whiskey and other alcoholic beverages;
  4. from thermal decomposition of limestone, CaCO3,
  5. in the manufacture of lime, CaO,
  6. as a by-product of sodium phosphate manufacture,
  7. directly from natural carbon dioxide springs, where it is produced by the action of acidified water on limestone or dolomite.

  • The two main ways that carbon enters the atmosphere is by combustion and bio process. CO2 or CO are the main two atmospheric carbon gases. Carbon monoxide is formed when a hydro-carbon fuel is burned without sufficient oxygen. This gas is still combustible this is what a catalytic converter does, it burns the unburned fuel and carbon monoxide into CO2. The modern gas engine does a poor job of efficiently burning fuel, mainly because the piston dynamics is so poor in a crank driven piston. Carbon is also part of many volatile chemicals which can evaporate into the air.
  • combustion
  • death & respiration
  • when people breathe, we release carbon dioxide, the gas for of carbon, into the atmosphere. with too few trees to use it to make oxygen, we have global warming.
  • When animals and plants respire, we release carbon dioxide into the atmosphere. In addition, some cars release fuels such as carbon dioxide.
  • by circulation
