How does fossil fuel combustion impact the carbon cycle?

Answer 1

The carbon cycle is a natural process whereby carbon moves in and out of the atmosphere, from the soil, oceans, animals and vegetation. It supports the greenhouse effect, where greenhouse gases have kept the earth comfortably warm since life began.

Fossil fuel is coal oil and natural gas that was laid down millions of years ago from the carbon of trees, vegetation and even animals. When man digs it up and uses it (by combustion, or burning), this extra carbon is released into the atmosphere, where it is accelerating the greenhouse effect. This accelerated, or enhanced, or runaway greenhouse effect is now causing global warming.

A:Excess carbon besides CO2 what we give off is put into the atmosphere by fossil fuel burning. A:The burning of fossil fuels by human affects the carbon cycle because burning of fossil fuel will release large amounts of carbon into the atmosphere causing the carbon dioxide rate to increase; Which eventually will create greenhouse effect, leading to global warming.

A:

The Carbon Cycle is a natural process by which Carbon Dioxide (a greenhouse gas) is exchanged between the 5 elements which make up the cycle:

1. the biosphere on land;
2. the oceans;
3. the atmosphere;
4. sediments;
5. the earth's interior.

Carbon dioxide along with other greenhouse gasses in the earth's atmosphere allows for the optimal living conditions on earth with regard to the sun's radiation reaching earth. Too little greenhouse gasses would make the world cold, too much would make it too warm.

The burning of fossil fuels ads additional man-made (anthropogenic) carbon dioxide to the cycle, primarily to the earth's atmosphere. Though some elements (primarily oceans and the biosphere) of this natural cycle are able to cope with some of these man-made carbon dioxide emissions, they cannot hold all, even though anthropogenic emissions are relatively minor. As a result of this, more and more man-made emissions are hold in the earth's atmosphere thereby directly affecting the "Greenhouse Effect". As a result, the earth's global temperature is rising.

Answer 2

Fossil fuel combustion releases carbon dioxide into the atmosphere, increasing its concentration. This excess CO2 contributes to the greenhouse effect, leading to global warming and climate change. It disrupts the natural balance of the carbon cycle by releasing more carbon into the atmosphere than can be naturally absorbed by plants and oceans.

Answer 3

Fossil fuels release a large amount carbon in the atmosphere , this leads to global warming because of the gree house effect.
