Answers

Answer 1
Answer:

Answer:

A. burning fossil fuels

Explanation:

Acid rain is caused, mainly by the emission of sulfur oxides and nitrogen oxides, which are gases commonly released into the atmosphere as a result of burning fossil fuels.

These oxides have the ability to interact with rainwater generating an acidic substance that is expelled from the clouds in the form of rain that has a very acidic pH.

The result of acid rain is the destruction of vegetables, the chemical alteration of water bodies, the death of aquatic animals, the contamination of groundwater and even the emergence of respiratory diseases and the destruction of public heritage.
