On my balance sheet for 2013, I would show an accounts payable of $1,000. During 2014, I paid my credit card company $900, so on my statement of cash flows as of December 31, 2014, I would show a negative $900 because I paid out $900 more than I received in cash for my accounts payable.
Where Fossil Fuels Come From. There are three major forms of fossil fuels: coal, oil and natural gas. All three were formed many hundreds of millions of years ago before the time of the dinosaurs â hence the name fossil fuels.The age they were formed is called the Carboniferous Period.It was part of the Paleozoic Era.ome deposits of coal can be found during the time of the dinosaurs. For example, thin carbon layers can be found during the late Cretaceous Period (65 million years ago) â the time of Tyrannosaurus Rex. But the main deposits of fossil fuels are from the Carboniferous Period.
Fossil fuels are fuels formed by natural processes such as anaerobic decomposition of buried dead organisms. The age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.Fossil fuels contain high percentages of carbon and include coal, petroleum and natural gas. Other more commonly used derivatives of fossil fuels include kerosene and propane.lthough fossil fuels are continually being formed via natural processes, they are generally considered to be non-renewable resources because they take millions of years to form and the known viable reserves are being depleted much faster than new ones are being made.
