GEOLOGY

Detailed explanation-1: -For an organism to become a fossil, it must not decompose or be eaten. This can happen if the organism either lives within or is moved to a place where it can be buried and kept from decaying.

Detailed explanation-2: -Dead organisms and waste products decay bringing the carbon into the ground. Overtime (millions of years) and under the right conditions some decomposed remains will be turned into fossil fuels such as coal and gas.

Detailed explanation-3: -Fossil fuels are burned to produce energy. In large power stations they are burned in the presence of oxygen. As the fuel burns the heat energy is used to heat water, as it is heated it produces steam which in turn rises and drives a turbine.

Detailed explanation-4: -When the animals die, they decompose, and their remains become sediment, trapping the stored carbon in layers that eventually turn into rock or minerals. Some of this sediment might form fossil fuels, such as coal, oil, or natural gas, which release carbon back into the atmosphere when the fuel is burned.
