Step-by-step explanation:
Acid Rain
What is acid rain
Acid Rain is any type of precipitation with acidic components that falls to the ground from the atmosphere. It can be wet or dry. When nitrogen oxides (NOx) and sulfur dioxide (SO2) are released into the atmosphere, they react with water and create sulfuric and nitric acids. These compounds can be carried away by air currents for hundreds of miles. They fall back to earth in the form of rain, sleet, hail, snow and dust.
Causes
Most acid rain is caused by humans in the form of burning of fossil fuels. A very small percentage of acid rain is caused by natural causes such as volcanoes or wildfires. The biggest source of acid rain producing pollutants comes from power plants that burn coal to produce electricity, as well as cars, trucks, busses and construction vehicles that emit nitrogen oxides and sulfur dioxide in the form of exhaust.
Effects of acid rain
The pollutants that cause acid rain also cause smog and fine particle pollution, both of which harm human health. Because sulfur- and nitrogen-based air pollution travel long distances, they are a problem for everyone -- and everything -- downwind of the smokestack or tailpipe, not just those in close proximity to power plants.
