What has been called a carbon sink?
Trees absorb carbon dioxide (when talking about a "carbon sink", it means the carbon as any form).
What is the cycle which includes an underground reservoir in the form of fossil fuels?
The carbon cycle is the cycle which includes an underground reservoir in the from of fossil fuels.
Which biogeochemical cycle includes a reservoir underground stored as fossil fuels?
Carbon Cycleor if you want to call it the Carbon/ Oxygen Cycle
How does carbon dioxide get underground?
You see, carbon dioxide grow little arms and legs to dig and run with. they always do this because they hate sunlight.
Can the natural cycle of carbon dioxide emissions increase carbon dioxide concentrations in the atmosphere?
No, the natural cycle of carbon dioxide (CO2) moves through the land, oceans and atmosphere, and has done for millions of years. It is able to remove all the natural carbon in the air (and part of the global warming carbon as well). It is the burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity that releases carbon that has been hidden underground for millennia that is increasing the carbon concentrations in the atmosphere.
Do you make coal out of fire?
No. Coal is carbon which has been compressed over thousands of years underground. The coal can then be used as a fuel.
Why would the levels of carbon dioxide have been increasing for the past 200 years?
200 years ago was the start of the Industrial Revolution when we started to seriously dig up and burn fossil fuels (coal, oil and natural gas). This burning released long-hidden reserves of carbon dioxide that had been hidden underground for 300 million years.
Will Carbon Sequestration increase ocean acidification?
Only if it is sequestered in the ocean. Carbon sequestration usually means storing the carbon dioxide underground in permanent water-and gas-tight reservoirs. This is a bold plan, but it has not yet been done successfully.
Why are these resources referred to as fossil fuels?
"Fossil fuels" refers to fuels, such as carbon and petroleum, that are generally believed to originate as fossils.
What cycle do humans affect by burning fossil fuels?
We affect the earth's regular carbon cycle by burning fossil fuels. Coal and oil combustion adds billions of tons of carbon to the atmosphere, carbon that has been stored underground for millions of years.
What has been called a carbon sink?
Trees absorb carbon dioxide (when talking about a "carbon sink", it means the carbon as any form).
What causes more carbon dioxide in the atmosphere?
Burning fossil fuels like coal and oil (as we do to power our vehicles and to produce electricity) releases extra carbon dioxide that has been hidden away underground for millions of years.
Burning coal produces the greenhouse gas carbon dioxide is this a false statement about the use of coal?
No, this is true. Coal is a fossil fuel which holds carbon which has been trapped underground for millions of years. When it is burnt the carbon dioxide is released where it adds to the greenhouse gases in the atmosphere.
What flammable gas is found underground?
carbon dioxide and water vapor
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 is the cycle which includes an underground reservoir in the form of fossil fuels?
The carbon cycle is the cycle which includes an underground reservoir in the from of fossil fuels.
How long have the carbon atoms in your body been on the earth?
Approximately 3.5 billion years; carbon, like all elements, is frangible.
