What are 5 processes that release carbin dixoide?
Cellular respiration in animals and plants releases carbon dioxide as a byproduct. Combustion of fossil fuels for energy production releases carbon dioxide into the atmosphere. Deforestation and land-use changes release carbon dioxide stored in trees and soil. Volcanic eruptions release carbon dioxide stored in the Earth's crust. Decay of organic matter, such as in composting or waste disposal, releases carbon dioxide as a result of microbial activity.
If you cut down a tree do you release the carbon that is stored in it?
Yes, when you cut down a tree and it decomposes or is burned, the carbon stored in the tree is released back into the atmosphere as carbon dioxide. This contributes to the increase of carbon dioxide levels in the atmosphere, a greenhouse gas that contributes to climate change.
What causes more carbon dioxide in the atmosphere?
Human activities such as burning fossil fuels (coal, oil, gas), deforestation, and industrial processes are the main sources of increased carbon dioxide in the atmosphere. These activities release carbon that has been stored for millions of years, leading to an imbalance in the carbon cycle and contributing to global warming.
What global impacts do bushfires have?
Bushfires release a lot of carbon dioxide that was stored in the trees and vegetation. Carbon dioxide mixes well with the air and the winds move it round the globe.
Why do biofuels not contribute to global warming even though burning biofuels releases carbon dioxide?
Biofuels are part of the natural carbon cycle, in which plants absorb carbon dioxide from the air and this becomes carbon which is eventually returned to the air when vegetation rots or is burnt, or when animals eat it and respire carbon dioxide back into the air. Thus, although burning of wood and biofuels does release carbon dioxide back into the air, this process does not add to the long term concentration of atmospheric carbon dioxide. When we create carbon dioxide from carbon that has been sequestered underground, we add new carbon dioxide to the air, increasing its concentration and causing global warming.
What effect does fuel have on the amount of carbon dioxide in the air?
Most of our fuel is fossil fuel, that is, coal, oil and natural gas. When these are used for fuel (by burning) they release carbon which has been stored in them for millions of years. This is adding to the amount of carbon dioxide (a greenhouse gas) in the atmosphere.
Where do scientists think extra carbon dioxide is coming from?
Scientists believe that the extra carbon dioxide in the atmosphere primarily comes from human activities, such as burning fossil fuels for energy, deforestation, and industrial processes. These activities release carbon that has been stored in the Earth for millions of years, contributing to the increase in atmospheric carbon dioxide levels.
Which increases the amount of carbon dioxide in the atmosphere acting as a carbon force?
Human activities such as burning fossil fuels, deforestation, and industrial processes increase the amount of carbon dioxide in the atmosphere. These activities release carbon that has been stored for millions of years, adding to the greenhouse effect and contributing to climate change.
When trees die do they release stored up carbon dioxide?
Well, trees don't really store carbon dioxide; they use the carbon dioxide directly to produce sugars during the Calvin cycle. When decomposers eat up those sugars, they release the carbon in the sugars in the form of carbon dioxide.
Carbon is stored in the atmosphere in the form of what molecule?
Carbon is stored in the atmosphere primarily as carbon dioxide (CO2) molecule.

Bushfires release a lot of carbon dioxide that was stored in the trees and vegetation. Carbon dioxide mixes well with the air and the winds move it round the globe.
Do plants release carbon dioxide when they decompose?
Yes, plants release carbon dioxide when they decompose because the process of decomposition involves the breakdown of organic matter, which releases carbon stored in the plants back into the atmosphere as carbon dioxide.
What is carbon dioxide naturally absorbed and stored in?
Carbon dioxide is naturally absorbed (through photosynthesis) and stored in trees and vegetation. It is also absorbed and stored in the oceans.
Which increase the amount of carbon dioxide in the atmosphereacting as a carbon source?
Burning fossil fuels and deforestation are two major human activities that increase the amount of carbon dioxide in the atmosphere, thus acting as a carbon source. When fossil fuels are burned, they release carbon dioxide, and when forests are cleared, the trees that once stored carbon release it back into the atmosphere.
