How did fossil fuels play a role in the carbon cycle fossil fuels require a lot of carbon to burn which releases carbon into the atmosphere fossil fuels are rich in carbon and burning them returns carbon to the soil fossil fuels require a lot of carbon to burn which takes carbon out of the atmosphere fossil fuels are rich in carbon and burning them releases carbon into the atmosphere

Fossil fuels played a significant role in the carbon cycle by releasing carbon into the atmosphere when burned. Fossil fuels are rich in carbon, and burning them emits carbon dioxide, a greenhouse gas, into the atmosphere. This leads to an increase in the concentration of carbon dioxide in the atmosphere, which contributes to global warming and climate change. Over time, the carbon stored in fossil fuels is released into the atmosphere, disrupting the natural carbon cycle and leading to environmental consequences.
