- Humans accelerate the loop by bringing carbon deposits and burning them for fossil fuels which then can lead to/cause Global warming.
Example of positive feedback:
- Increase c02 in the atmosphere leads to warmer climate which leads to more weathering
- More weathering of organic carbon leads to increase in carbon dioxide
- These feedback loops take years to act.
- In real life, these organic carbon sedimentary deposits are deep below the surface and weathering cannot occur.
- It is limited by how much is exposed to the earths surface.
- Carbon is removed from the atmosphere when fauna in the ocean concerts it to solid carbonates.
- Earth will not overheat due to positive feedback loop.
- It will not overheat because it takes up a long time.
- Oxygen-->fossil fuels--> then humans combust them and it makes carbon dioxide and water.
- This gets absorbed by plants through photosynthesis and oxygen is released.
- Plants get eaten by animals.
- They die and decompose and turn into fossil fuels and cycle starts over.
- Also the death and decay of animals and plants and their breathing or respiration makes water and carbon dioxide or the 2nd step of the cycle.
