what is Coal, Oil and Natural gas. We use/burn them for energy. the deffiniton of??????????????
Coal, oil, and natural gas are all fossil fuels, which are formed from the remains of plants and animals that lived millions of years ago.
Coal: Coal is a black or brownish-black sedimentary rock that is primarily composed of carbon. It is formed from the remains of plants that lived and died in swamps and marshes. Coal is a highly combustible fuel and is mainly used for electricity generation in power plants, as well as for industrial processes such as steel production and heating.
Oil: Oil, also known as petroleum, is a liquid fossil fuel that is predominantly made up of hydrocarbons. It is formed from the remains of marine plants and animals that were buried in ancient oceans and subjected to high heat and pressure over millions of years. Oil is extracted from underground reservoirs through drilling and is refined into various products such as gasoline, diesel fuel, jet fuel, and heating oil. It is widely used for transportation and as an energy source in various industries.
Natural Gas: Natural gas is a naturally occurring mixture of hydrocarbon gases, primarily methane (CH4). It is found alongside oil reservoirs and coal deposits, as well as in deep underground rock formations. Natural gas is colorless and odorless in its pure form. It is extracted through drilling and is used as a fuel for heating, electricity generation, cooking, and as a raw material in various industrial processes. Natural gas is also considered a cleaner-burning fossil fuel compared to coal and oil, as it emits fewer greenhouse gas emissions when burned.
