Rain helps to cleanse the air by washing away pollutants and particles that are present in the atmosphere. When it rains, it acts as a natural purifier by removing harmful substances such as dust, pollen, and pollutants like sulfur dioxide and nitrogen oxides from the air. This process is known as "wet deposition." Additionally, rain can also help to reduce the concentration of airborne particles by causing them to settle on the ground or be washed away into bodies of water. Overall, rain can help to improve air quality by reducing the presence of pollutants in the atmosphere.
