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 combustion. We understand today that humanity’s use of fossil fuels is severely damaging our environment. Fossil fuels cause local pollution where they are produced and used, and our ongoing use is causing lasting harm to the climate of our entire planet.

Answer:
TRUE
Explanation:
The earth is comprised of three distinct layers namely the core, mantle and the crust. The core is the extreme interior layer which is comprised of the denser elements like iron, nickel and other siderophile elements. Thee denser minerals are deposited, by sinking into the core of the earth forming the highest density layer. The core was formed about 1 to 1.5 billion years back.
Whereas, the least dense elements were concentrated in the upper region of the earth forming the crust. These are the lighter elements so it did not get sink into the bottom. But still many of these elements are found in association with the core rocks. There occurred constant evolution on the crustal portion of the earth.
Thus, these elements are found in larger proportions in the crust and were formed during the initial formation of the earth.
Hence, the above-given statement is True.
