15 Explain the causes of acid rain.
Answers
Explanation:
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
Answer:
1. Most of the electric power supporting the modern-day energy requirements comes from combusting fossil fuels such as oil, natural gas, and coal that generate nitrogen oxides (NOx) and sulfur dioxide (SO2) as the chief contributors to acid rain.
2. Erupting volcanoes contains some chemicals that can cause acid rain.
3. Apart from this, the burning of fossil fuels, the running of factories and automobiles due to human activities are a few other reasons behind this activity.
