Answer 2

Acid rain and marble cancer:

Explanation:

• Acid rain, also known as acid deposition, refers to any sort of precipitation that contains acidic components, such as sulfuric or nitric acid, that falls to the ground wet or dry from the atmosphere. Acidic rain, snow, fog, hail, and even dust can all contribute to this.

• When sulphur dioxide ($SO_2$ ) and nitrogen oxides ($NO_X$) are released into the atmosphere and carried by wind and air currents, acid rain occurs. Sulfuric and nitric acids are formed when $SO_2$ and $NO_X$ react with water, oxygen, and other molecules. They descend to the ground after interacting with water and other substances.

• Acid rain causes marble cancer, which is the progressive corrosion (or eating away) of a monument's marble. Marble cancer is primarily caused by acid rain. Manufacturers emit a variety of gases, including sulphur dioxide and nitrogen oxides.
