Fossil fuels are classified as non-renewable sources. Examples of fossil fuels are coal and petroleum. They are termed non-renewable because they were produced organically over millions of years. if the limit quantity of fossil fuels are used up, it will be difficult to replace them.
What else can I help you with?
What can fossils include?
Fossil fuels are formed by natural resources such as dead organisms by decomposition (aerobic or mostly anaerobic). Fossil fuels have high percentages of carbon. It includes coal petrol diesel natural gas etc. It ranges from volatile materials like petrol to nonvolatile materials like coal.
What are animal fuels?
biofuels
Are fossil fuels found in sedimentary rock?
Yes.
How does the burning of fossil fuels affect the environment?
Burning fossil fuels, especially coal, is a dirty process. Incomplete combustion of coal and oil produces particulate matter. Heavier particulates produce an annoying dirty grit, and lighter particulates can be inhaled deeply and become a health hazard. In addition to the desired combustion of organic molecules, impurities such as sulfur also burn and produce potentially dangerous oxides. Since the air is made of 80% nitrogen, nitrogen is combusted along with the fuel at high temperatures, releasing nitrous oxides. Since fossil fuels are composed mainly of carbon by weight, all fossil fuels produce carbon dioxide when burned. In the atmosphere, the sulfur and nitrous oxides produce sulfuric acid and nitric acid, respectively, which can lead to acid rain. The carbon dioxide helps trap heat in the atmosphere - contributing to the potential warming of the earth. In this lecture-discussion we will examine major local, regional, and global environmental effects of burning fossil fuels. These are respectively particulates, smog and acid rain, and global warming. The importance of particulates has long been acknowledged, and major particlulate emissions control measures have been launched in many countries. Evidence for acid rain is readily available, and the effects from impact on forests and lakes to crumbling ancient Greek structures have confirmed its presence, but its overall environmental/economic importance remains a matter of controversy. It is now widely accepted that human activities have contributed to a noticeable average global warming trend in the twentieth century. However, there are differential impacts of this global trend on regional climate, agriculture, storm damage, and other effects in different parts of the world. This complicates both the assessment of global effects of atmospheric emissions and international negotiations over requisite changes in fossil fuel use.
Why did geologists develop the geologic time scale?
The geological time scale is the geologic history of the planet from formation to the present. It starts with large divisions of time called eons and is subdivided into successively smaller units of time based on dominant lifeforms, extinction events, even climate. The development of the geologic time scale was initially based on the observation and reasoning that deeper layers of rock are generally older than less deep layers in what is called the "Law of Superposition".Paleontologists look for index fossils in fossil bearing sedimentary rock. Index fossils are organisms that were widespread, rapidly evolving, and only existed for a short period of time as evidenced by their appearance in the fossil record of specific rock strata. The appearance of a fossil alongside an index fossil gives a rough approximation of the age of the fossil in relative terms as it would appear on the geologic time scale. The appearance of the same fossil alongside index fossils of different geologic ages means that the fossil organism spanned multiple geologic time periods. Associations of specific strata alongside radiographically datable igneous and metamorphic rock determines the absolute age of a fossil.A period of around 4,600,000,000 years, the largest groupings of geologic time are eons, followed in descending order by era, period, epoch, and age.The geologic time scale is very important, especially in fields involving the exploration and retrieval of fossil fuels, which are geologically date range specific.
What are some slogans about fossil fuels?
Bury Fossils get Fuels
What did fossils fuels get their energy from?
The sun.
Are natural gases fossils fuels?
yes
Why fossils fuels are called non renewable form of energy?
Fossils fuels are called non renewable because we consume them faster then they can replaced naturally
Why are fossil fuels called Fossil fuels if there is no fossils?
theyre made out of dead stuff
Which fossils fuels are going to run out first?
the answer is coal
Why petroleum and natural gas are known as fossils fuels?
petroleum and natural gas are none other than the decomposed forms of plants and animals that had been buried under the earth before millions of years.The decomposed forms from which fuels are obtained are termed fossils and therefore the fuels obtained from the fossils(petroleum , natural gas etc) are termed fossil fuels
What are fossle fuels?
fossil fuels are natural gasses that come from fossils. one fossil fuel is oil.
Fossils fuels are coal and what else?
Oil and natural gas.
How is most of the electricity in the Unites States generated?
Fossils fuels
What are the fossils fuels name?
Oil , coal, and natural gas
What are 4 fossils fuels and why are they called fossil?
oil, coal, natural gas, coke they are called fossil fuels because they are as old as fossils. They take thousands, if not millions of years to turn into what they are.
