$\huge\tt\red{AnsWer:-}$

$\boxed{\boxed{\boxed{\boxed{\purple{ Harmful\: effect\: of \: burning \: of \:fossil \:fuels} }}}}$

• Carbon fuels such as wood, coal, petroleum release unburnt carbon particles in the environment. These particles are very dangerous pollutants and cause respiratory diseases for example asthma.

• When fuels are incompletely burnt, they release carbon monoxide gas into the atmosphere. This gas is very dangerous as it is poisonous in nature. If we burn coal in a closed room, then the person sleeping in that room will be killed by the action of carbon monoxide.

• The combustion of fossil fuels also releases a large amount of carbon dioxide into the atmosphere. Carbon dioxide is a greenhouse gas which is responsible for global warming. Global warming is a rise in the overall temperature of earth’s surface. This leads to melting of polar caps and rise in the sea level and further results in flooding of coastal regions.

• Burning of coal and diesel releases sulphur dioxide gas. This gas is extremely corrosive and suffocating in nature. Petrol gives off oxides of nitrogen. The oxides of sulfur and nitrogen get dissolved in rainwater and form acids. This is known as acid rain. This water is very harmful to plants, animals, and various monuments

Answer 2

${ \huge{ \underline{ \underline{ \mathrm{ \purple{ answer}}}}}}$

BURNING OF FOSSIL FUELS:

➡The burning of fossil fuel gives out harmful compounds like sulfur dioxide and nitrogen oxides. These substances will rise terribly high into the atmosphere, wherever they combine and react with water, oxygen, and other chemicals to form a lot of acidic pollutants, called air pollution.

WATER POLLUTION :

➡Some of these water-borne diseases are Typhoid, Cholera, Paratyphoid Fever, Dysentery, Jaundice, Amoebiasis and Malaria. Chemicals in the water also have negative effects on our health. Pesticides – can damage the nervous system and cause cancer because of the carbonates and organophosphates that they contain.
