Question

The phenomenon of marble cancer is due to

Answer 1

Acid rain

• When the pH of the rainwater drops below $5.6$, it is called acid rain.
• “Acid rain refers to the ways in which acid from the atmosphere is deposited on the earth’s surface.”
• Acid rain harms trees, crops, and plants by dissolving and washing away nutrients required for growth.
• Buildings and other structures composed of stone or metal are harmed by acid rain.

Marble cancer

• Pollutants in the air, such as Sulphur dioxide and Nitrogen dioxide, react with water vapour in the atmosphere to produce Sulphuric acid and Nitric acid, respectively.
• These acids react with rain, causing it to become acidic.
• Marble cancer is a phenomenon caused by acid rain corroding building materials like marble.

So, the phenomenon of marble cancer is due to acid rain.
