Question

burning of fossil fuels ​

Answer 1

Answer:

Coal and petroleum are fossil fuels found in earth’s crust. They are non-renewable and exhaustible resources. They must be conserved to get their advantage in present and future.

The burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2).

The burning of fossil fuels by industry, households and vehicles releases gaseous emissions of sulphur dioxide and oxides of nitrogen that can travel hundreds of miles in the atmosphere. These gases can be dissolved in rainwater to form sulphuric and nitric acids. These will subsequently be deposited on soil and result in soil acidification, soil eutrophication and structural damage to soil minerals. The acid rain may reach the water resources and contaminate. Oil may end up in soil or water in raw form, for example during oil spills.

We can reduce pollution by fossil fuel

• By reducing the use and burning of fuels .

• By using more efficient machines that will emit less pollutant .

• By introducing techniques of treating the pollutant before emitting in the atmosphere .

• By using alternative safer, eco- friendly technologies.

Answer 2

Burning of fossil fuels such as petroleum and coal results in air pollution. This is because burning of fuels in thermal power plants and automobiles releases harmful chemicals such as oxides of sulphur and nitrogen into the air.
