Question

Burning of fossil fuels leads to
A.Pollution
B.Global warming
C.Both
D.None

Answer 1

Hint: Fuels are chemicals that may be used as energy sources. Fossil fuels are buried biological materials that can be transformed into crude oil, coal, natural gas, or any heavy oil by applying pressure and heat to the earth's crust over hundreds of years.

Complete answer:
A good fuel is one that is inexpensive to get and generates a reasonable quantity of heat when burned. The calorific value of a kilogramme of fuel is the quantity of energy it produces. An ideal fuel is one that burns fully in the air at a reasonable rate and generates a big quantity of energy. No fuel possesses these qualities, thus optimal fuel is difficult to come by.
When fossil fuels are burned, hazardous compounds are released into the environment. Increased gasoline use has negative consequences for the environment. These consequences will be clearly depicted in the following points:
Unburned carbon particles are released into the environment by carbon fuels such as wood, coal, and petroleum. These particles are very hazardous contaminants that induce respiratory illnesses such as asthma.
When fuels are burned inefficiently, carbon monoxide gas is released into the environment. Because it is toxic, this gas is extremely hazardous. If we burn coal in a confined room, the carbon monoxide produced will kill the person sleeping in that room.
Fossil fuel combustion also emits a significant amount of carbon dioxide into the environment. Carbon dioxide is a greenhouse gas that contributes to climate change. A rise in the total temperature of the earth's surface is referred to as global warming. This causes polar ice caps to melt and sea levels to increase, resulting in coastal flooding.
Sulphur dioxide gas is produced when coal and diesel are burned. The composition of this gas is very caustic and suffocating. Nitrogen oxides are emitted by petrol. Acids are formed when sulphur and nitrogen oxides dissolve in rainfall. Acid rain is the term for this. This water is extremely hazardous to flora, animals, and historical sites.
Hence option C is correct.

Note:
Climate change encompasses both global warming caused by human-caused greenhouse gas emissions and the accompanying large-scale weather pattern alterations. Though there have been earlier times of climatic change, people have had an extraordinary influence on Earth's climate system and caused worldwide change since the mid-twentieth century.
