Look at the diagram above. What are the materials that are types of carbon * 4 points sink or long term carbon storage (these have not been decomposed).

Question

Check all that apply.
Coal
Peat
Natural Gas
Oil

Answer 1

In the context of carbon storage, the materials that can be classified as long-term carbon sinks are:

• Coal: This is a fossil fuel formed from decomposed plant material over millions of years, and it stores carbon for long periods.
• Peat: This is a type of soil made up of partially decomposed organic matter, primarily from plant material, and it also acts as a long-term carbon storage mechanism.

Natural Gas and Oil, while they are fossil fuels, are typically considered more transient forms of carbon storage, as they are once extracted and burned, they release the stored carbon back into the atmosphere.

So, the correct answers are Coal and Peat.
