Explain circumstances leading to acid rain. How does acid rain affect us?
The burning of fossil fuels, petrol and diesel releases harmful gases in atmosphere like Sulphur Dioxide and Nitrogen Dioxide
These gases get mixed with water vapour present in the atmosphere.
And form harmful acids like Sulphuric Acid and Nitric Acid
These acids dissolve in rainwater and fall to the earth in the form of rainwater
This is called acid rain
Harmful effects of Acid Rain
Acid rain effects both living and non living things
It damages the leaves of the plants and decreases the fertility of the soil
Animals and Humans
Acids present in the acid rain makes it difficult for humans and animals to breathe
Acid rain causes the water in ponds, lakes and rivers to become more acidic and hence unsuitable for survival of aquatic plants and animals
- Non Living things
Monuments and building get discoloured due to acid rain
Example - Acid Rain has caused white marble of Taj Mahal to turn yellow
