Question

Damage of Taj Mahal is being caused by
A) Acid rain
B) Dust
C) Global warming
D) Smoke

Answer 1

Hint: Taj Mahal is one of the Seven Wonders of the World located at Agra in India. The once white Taj Mahal is turning yellow and the marble is severely affected. This area is heavily polluted because of the emission of gases and other pollutants present in the air like oxides of sulphur nitrogen carbon etc.

Complete answer:
Agra is a highly populated city. The population leads to many environmental problems like air pollution. The gases emitted from the vehicle, nearby factories and the refinery located at Mathura emit gaseous pollutants which are rich in gases like sulphur dioxide, nitric oxide. This sulphur dioxide when mixed with rain water forms acid rain whose pH is less than 5. This acid rain is very dangerous as it corrodes metals, marbles and stones.

Dust- It is made up of solid particles mixed with air. Generally the soil gets mixed with air due to moving winds. It causes temporary damage.

Global warming- It is defined as the rise in the temperature of the earth due to the presence of greenhouse gases.

Smoke- It is the emission released by the vehicles factories which causes several respiratory disorders. It is indirectly affecting the damage.

Hence the correct answer is option ‘A’.

Note: Several steps are being taken to restore Taj Mahal. A layer of clay mineral is applied on the Taj Mahal which protects it from the adverse effect of acid rain. It pulls away the impurities from the surface and can be washed off with water. The other step taken is stopping the use of coke and coal in the Taj trapezium zone and also the natural gas is used instead of other mineral fuel.
