Sources of carbon dioxide

Carbon dioxide is a drab gas with a thickness of about 60% higher than that of dry air.sources of carbon dioxide are the weathering of carbonate rocks, breathing, and decomposition, elimination of forests, human Resources, natural sources. and also here Weathering of carbonate rocks.

What is carbon dioxide

Carbon dioxide, (CO2), a colorless gas that has a weak and sharp smell and a sour taste; It is a minor component of the Earth’s atmosphere (approximately 3 volumes in 10,000), formed in the combustion of carbon-containing materials, in the fermentation and respiration of animals and used by plants in carbohydrate photosynthesis. The presence of gas in the atmosphere prevents part of the radiant energy received by the Earth from being returned to space, thus producing the so-called greenhouse effect. Industrially, it is recovered for numerous diverse applications of flue gases, as a byproduct of the preparation of hydrogen for the synthesis of ammonia, from limekilns and other sources.

Sources of carbon dioxide

sources-of-carbon-dioxide

sources of carbon dioxide are the following:

Weathering of carbonate rocks

Limestone is exposed to air and weathering as the Earth ages, due to tectonic processes or changes in sea level. Carbonic acid is formed by the dissolution of carbon dioxide in water, causing carbon melt to dissolve, resulting in the spread of carbon dioxide.

Breathing and decomposition

Carbon dioxide is released when organisms breathe, and in the process of cellular respiration, breathing cells, to produce the energy that organisms need by combining glucose and oxygen from the air, and then converting to energy, and carbon dioxide when the cell is breathing. This is the process by which organisms decompose, when organisms die by bacteria, releasing carbon dioxide into the atmosphere and water.

Human Resources

Part of the carbon dioxide comes from the daily activities of humans. These activities include power generation, transportation, industries, chemical production, oil production, some agricultural practices, as well as the burning of fossil fuels (coal, oil, natural gas) which is the main cause of emissions. Carbon dioxide, in addition to producing electricity that causes 40% of CO2 emissions.

Natural sources

In addition to other sources mentioned above, natural sources are responsible for the majority of atmospheric CO2 emissions, including:

  • The oceans, where they provide the largest annual amount of carbon dioxide, to any natural or human source.
  • Forest fires, emissions from volcanic eruptions.

Elimination of Forests

Carbon dioxide is released from trees when it is cut, for the purpose of producing goods or heating, the carbon normally stored by trees for photosynthesis, according to research published by Duke University. Deforestation, according to the Global Forest Resources Assessment 2010.
