Clayton 2 thick. If this occurs over millions of years without being cleared out, the result will be crude oil stored very deep underground. The problem with crude oil is obvious: it is a finite source of chemical energy due to the fact that we use it billions of times faster than it is produced. Because this production – reproduction ratio is so off balance, at some point all of the crude oil on the planet will eventually be nonexistent. One of the fossil fuels widely used today is coal. Coal is a solid matter that is found deep underground. Coal is a form of carbon chains, much like crude oil. Coal is most often used in cases where a longer lasting burn is needed. Coal is generally used to cooking, and steam engines. There are coal power plants, but they are becoming obsolete as the evidence for their environmental harm becomes more apparent. Energy is extracted from these fuels by burning them. When heat is applied to hydrocarbon chains, a chemical reaction takes place. The splitting of hydrocarbon chains is what is known as an exothermic reaction. What this means is: as the reaction takes place, namely splitting carbon-carbon and carbon-hydrogen bonds, energy is released. In this case the energy is released as heat, and in the case of the combustion engine; expansion force in addition. One problem associated with fossil fuels is their emissions. As these hydrocarbon chains are broken apart to release their energy, they are required by the laws of nature to reform new compounds. The most abundant newly formed compound produced in this method is called carbon dioxide, or CO2. Carbon dioxide is easily formed, and hard to get rid of. The problem with carbon dioxide is that it is known as a greenhouse gas. There are many forms of greenhouse gases, but by far the most abundant in our atmosphere today is carbon dioxide. What this means is as heat energy from the sun enters our atmosphere is warms the planet’s surface.
What carbon dioxide does is it traps some of that heat and keeps it from being
