How Does Carbon Leave Land Plants?
When a plant dies, it decomposes into the soil, and sometimes creates a fossil, which is used for most human-made things that need to be powered.
All fossil fuels are just plants. Coal is a fossil fuel made of plants that died about 100 - 400 million years ago. Coal is a nonrenewable energy source because it takes millions of years to form. |
