Explanation:

Fossil fuels are mixtures of substances that can be burne to obtain energy like coal, petroleum and natural gas.

They are formed by organic matter, mainly carbon and hydrogen, along with other elements.

The theory with the most consensus on the formation of fossil fuels is that they formed after organic matter, plants and animals, died and were buried under a huge mass of sediments.

The huge pressures, in the absence of oxygen, yield the decomposition of the organic matter to form the fossil fuels.

Due to the fossil fuels require million of years to be formed they are considered nonrenewable energy resources, as they cannot possible be formed in a reasonable time on human life scale.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
