As you have asked about the meaning of fossil fuels, I am giving you some information about it, check below for the details

Fossil fuels are fuels formed by natural processes such as anaerobic decomposition of buried dead organisms.

Fossil fuels are sources of energy that have developed within the earth over millions of years.
Because fossil fuels - oil, natural gas, and coal - take so long to form, they are considered nonrenewable.

The age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.
Fossil fuels contain high percentages of carbon and include coal, petroleum and natural gas
The use of fossil fuels raises serious environmental concerns.

Petroleum and natural gas are formed by the anaerobic decomposition of remains of organisms including phytoplankton and zooplankton that settled to the sea (or lake) bottom in large quantities under anoxic conditions, millions of years ago. Over geological time, this organic matter, mixed with mud, got buried under heavy layers of sediment.

The resulting high levels of heat and pressure caused the organic matter to chemically alter, first into a waxy material known as kerogen which is found in oil shales, and then with more heat into liquid and gaseous hydrocarbons in a process known as catagenesis.

Fossil fuels are of great importance because they can be burned (oxidized to carbon dioxide and water), producing significant amounts of energy per unit weight
