Which of the following is NOT a fossil fuel? a)Coalb)Woodc)Petroleumd)...
The correct answer is
Wood.
- For centuries,
wood
was used as domestic
and industrial fuel.
- In many r
ural parts
of our country, people still use wood as a fuel because
of its easy availability and low cost
. - However,
burning wood
gives a lot of smoke
which is very harmful
to human beings. - It causes
respiratory problems
. - Since wood burns to produce
unwanted byproducts,
it is not environmentally friendly.
- Wood is obtained from trees and is a naturaual resource and is not formed as a result of organic decomposition of living organisms.
Unlike coal or crude oil, wood does not remain of a prehistoric organism, and
therefore it is not fossil fuel - it's just fuel. Coal
is one of the fuels used to cook food. - Earlier, it was used in railway engines to produce steam to run the engine.
- It is also used in thermal power plants to produce electricity. Coal is also used as fuel in various industries.
Petroleum
was formed from organisms living in the sea. - As these organisms died, their bodies settled at the bottom of the sea and got covered with layers of sand and clay.
- Over millions of years, absence of air, high temperature and high pressure transformed the dead organisms into petroleum and natural gas.
- A natural fuel such as coal or gas, formed in the geological past from the remains of living organisms.

Wood is NOT a fossil fuel
Wood is a renewable source of energy that comes from trees and plants, while fossil fuels are non-renewable resources that come from the remains of ancient plants and animals.
Explanation:
- Coal: Coal is a fossil fuel formed from the remains of plants that lived millions of years ago. It is extracted from underground mines and used for electricity generation and heating.
- Petroleum: Petroleum, also known as crude oil, is a fossil fuel that is extracted from underground reservoirs. It is refined to produce various products such as gasoline, diesel, and jet fuel.
- Natural Gas: Natural gas is a fossil fuel that is primarily composed of methane. It is extracted from underground rock formations and used for heating, cooking, and electricity generation.
- Wood: Wood is a natural material that comes from trees and plants. It is considered a renewable resource because trees can be replanted and harvested sustainably. Wood is used for construction, furniture, and as a source of heat energy.
In conclusion, wood is not a fossil fuel because it is a renewable resource that comes from living organisms, unlike coal, petroleum, and natural gas which are derived from ancient organic matter.
