Question

Fossil fuels are the
(A) dead remain of the living organism
(B) coal mines
(C) carbon black
(D) living organism

Answer 1

Hint: Fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas. Peat is also sometimes considered a fossil fuel. fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources.

Complete answer:
A fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing organic molecules originating in ancient photosynthesis that release energy in combustion. Such organisms and their resulting fossil fuels typically have an age of millions of years, and sometimes more than 650 million years. Commonly used derivatives of fossil fuels include kerosene and propane. Fossil fuels range from volatile materials with low carbon-to-hydrogen ratios (like methane), to liquids (like petroleum), to nonvolatile materials composed of almost pure carbon, like anthracite coal.
Crude oil, or petroleum (literally “rock oil” in Latin), is a liquid fossil fuel made up mostly of hydrocarbons (hydrogen and carbon compounds). Oil can be found in underground reservoirs; in the cracks, crevices, and pores of sedimentary rock; or in tar sands near the earth’s surface.
Coal is a solid, carbon-heavy rock that comes in four main varieties differentiated largely by carbon content: lignite, sub-bituminous, bituminous, and anthracite.

Hence the correct option is A option.

Note:
Unearthing, processing, and moving underground oil, gas, and coal deposits take an enormous toll on our landscapes and ecosystems. The fossil fuel industry leases vast stretches of land for infrastructure such as wells, pipelines, access roads, as well as facilities for processing, waste storage, and waste disposal.
