They were formed fr
2、om ancient plants and organisms during the carboniferous period ( 石炭纪) approximately 360 to 286 million years ago even before the age of dinosaurs. At that time the land was covered with swamps filled with organisms and plants. As they died they sank to the bottom of the swamps and oceans, and over
3、millions of years started decomposing under layers of sand, clay, and other minerals. Different types of fossil fuels formed depending on the combination of organic matter, temperature, time and pressure conditions while decomposing.There are three major types of fossil fuels: coal, oil, and natural
4、 gas. Coal was formed from ferns, plants and trees which hardened due to pressure and heat. Oil was formed from smallorganisms like zooplankton (浮游动物) and algae (藻类), for pressure caused the more complex organic matter to decompose. Natural gas was formed by the same process as oil, (but) only was e
5、xposed to more heat and pressure, causing it to further decompose and turn into a gaseous (气态) form.Fossil fuels are sought -after energy sources because they have a high energy density. They are the worlds dominant energy source. Fossil fuels have a variety of applications from electricity producti
6、on to transport fuels. They can also be used to make a variety of common products from plastics, to cosmetics, to even some medicines. These resources have powered industrialization over history and continue to do so today.Fossil fuels can be an abundant and cheap, or in some cases, a scarce and exp
7、ensive form of energy, depending on geographic location. For this reason, geopolitical issues arise due to scarcity caused by the natural geographic allocation of these highly valuable resources. Fossil fuels are considered non-renewable resources because they take millions of years to form, which m
8、eans that once they are used the resources will not be replenished in a human lifetime.The gradual depletion of the most accessible fossil fuel reserves have has forced companies to develop technologies for extracting more challenging or unconventional reserves. In many cases, this means additional
9、safety and environmental concerns as well as higher costs. Fossil fuels are also the largest emitters of carbon dioxide a greenhouse gas which causes climate change. In addition, their production causes both environmental and human health issues. These concerns have triggered society to look at alte

17、c deviceprocessthe environmentTeachers referenceYour carbon footprint is the sum of all emissions of CO2 (carbon dioxide), which were induced by your activities in a given time frame. When you drive a car, the engine burns fuel which creates a certain amount of CO2, depending on its fuel consumption
18、 and the driving distance.When you heat your house with oil, gas or coal, then you also generate CO2. Even if you heat your house with electricity, the generation of the electrical power may also have emitted a certain amount of CO2. When you buy food and goods, the production of the food and goods,
