It is one of the most magnificent monument present in India. It was built by emperor Shah Jahan for his beloved wife Nur Jahan. This monument is made by pure marble with tremendous effort. But if you compare the Taj mahal earlier with Taj mahal in present day, you will see that its colour has changed to light yellow. What could have happened?]]> 2022-01-07 14:49:34 UTC https://padlet.com/dramesh2474/lhu8vmycom18ywt1/wish/1980631668 dramesh2474 https://padlet.com/dramesh2474/lhu8vmycom18ywt1/wish/1980644436 When coal and petroleum are burned in automobiles, electric power plants, and factories, they release certain harmful gases into the air. When it starts to rain, These gases combine with the water drops in the air to form sulfuric acid, Nitric acid and carbonic acid. The presence of these gases in the water drops makes the rain acidic. This rain is called acid rain. Acid Rain, as the name suggests, can be said to be the precipitation of acid in the form of rain in the simplest manner. When atmospheric pollutants like oxides of nitrogen and sulfur react with rainwater and come down with the rain, then this results in Acid Rain. So acid rain is the rain which has excess of acids in it.]]> 2022-01-07 14:56:06 UTC https://padlet.com/dramesh2474/lhu8vmycom18ywt1/wish/1980644436 dramesh2474 https://padlet.com/dramesh2474/lhu8vmycom18ywt1/wish/1981426709

Acid rain is very harmful to agriculture, plants, and animals. It washes away all nutrients which are required for the growth and survival of plants. Acid rain affects agriculture by the way it alters the composition of the soil.

Acid rain goes into the rivers and lakes and pollutes it. This effects the aquatic ecosystem.

Acid rain also causes the corrosion of metals.

It damages buildings and monuments made of stone and marble

Taj Mahal, one of the 7 wonders of the world, is largely affected by acid rain. The city of Agra has many industries which emit the oxides of sulphur and nitrogen in the atmosphere. This causes the formation of acid rain. Acid rain has the following reaction with the marble which is calcium carbonate.
CaCO₃ +  H₂SO₄ → CaSO₄  + H₂O + CO₂ 
The formation of calcium sulphate results in the corrosion of this beautiful monument.]]> 2022-01-08 04:36:16 UTC https://padlet.com/dramesh2474/lhu8vmycom18ywt1/wish/1981431784 dramesh2474 https://padlet.com/dramesh2474/lhu8vmycom18ywt1/wish/1981438372

One of the precaution that we can take against acid rain is having a check at the emission of oxides of nitrogen and sulphur.

We can reduce the burning of fossil fuels which will reduce the emissions of oxides of sulphur and nitrogen.

we can spread awareness about this issue too.
