carbon is an element, so "carbon" can't exist of anything.
But the carbon found in fossil fuels are mostly from shells and dead animals or plants, after being exposed to imense heat and presure by stacking layers of sediment, plants and shells
The carbon cycle is most affected by the burning of fossil fuels. When fossil fuels are burnt, carbon dioxide is released into the atmosphere, contributing to the greenhouse effect and global warming. This disrupts the natural balance of the carbon cycle, leading to various environmental impacts.
Carbon Most common in all fossil fuels is carbon. In natural gas, both hydrogen and carbon are common.
The burning of fossil fuels, such as gasoline and coal, produces the most carbon monoxide.
When fossil fuels are burned, carbon dioxide is released into the environment. This can influence the greenhouse effect and increase global warming. Coal is the fossil fuel that produces the most carbon dioxide emission.
atmosphere
Coal is the fossil fuel that emits the most carbon dioxide when burned, due to its high carbon content compared to other fossil fuels like oil and natural gas.
When fossil fuels are burned, carbon dioxide is released into the environment. This can influence the greenhouse effect and increase global warming. Coal is the fossil fuel that produces the most carbon dioxide emission.
Carbon dioxide (CO2) is the gas released from burnt fossil fuels. It is the most significant gas contributing to global warming.
Burning fossil fuels.
The most important source of carbon entering atmosphere is industries. Living things, burning fossil fuels and automobiles are other sources of carbon dioxide.
Fossil fuels.
Most, if not all, roller coasters are powered by electricity. Most electricity is still being generated by burning of fossil fuels (coal, oil and natural gas). As this burning emits carbon dioxide you can clearly say that roller coasters are contributing to global warming by using fossil fuels.
