Explain circumstances leading to acid rain. How does acid rain affect us?

 

Answer

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 

 

  • Plants

 

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
  • Aquatic Life
    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
