Formed when chemicals in the the air get into rain and end up the acidity levels

Acid rain

Explanation:

Acid rain is a phenomenon that has arisen with the increasing industrialization of the world, in direct relation to air pollution, manifesting itself with greater intensity and greater comprehensiveness in the developed countries.

Smoke emissions from coal-based thermoelectric plants, pulp mills, refineries, automotive vehicles, as well as any gaseous pollutants released into the atmosphere, contribute to the formation of acid rain. Sulfur and nitrogen compounds are the main components of this rain, which can manifest both at the place of origin and hundreds of miles away.

In gases produced by factories and engines (especially when coal is burned), sulfur oxides (SO2) are released into the atmosphere, which react with water vapor to produce sulfuric acid (H2SO4), which is diluted in rainwater and giving rise to acid rain, with very acidic pH.

This type of rain, when frequent causes acidification of the soil, also damaging plants and animals, the life of rivers and forests. In the same way the buildings present in the area are affected.
