Clouds or raindrops containing harmful chemicals are called acid rain. Acid rain is caused by pollutants in the atmosphere, such as sulfur dioxide and nitrogen oxides, mixing with water vapor to create sulfuric acid and nitric acid in the precipitation. Acid rain can have detrimental effects on the environment, including damaging vegetation, aquatic ecosystems, and infrastructure.
Clouds help protect the planet by reflecting sunlight back into space, which helps regulate the Earth's temperature. They also play a role in the water cycle by producing precipitation, which is essential for providing fresh water to plants, animals, and humans. Additionally, clouds can act as a shield against harmful ultraviolet radiation from the sun.
