Sulfur dioxide is a colorless and extremely polluting gas, resulting from the burning of fossil fuels.
The impurities of fossil fuels allow this gas to be released into the atmosphere, whenever this type of fuel is burned. The activities that most promote the burning of fossil fuels are the burning of diesel oil in vehicles and the burning of coal and oil in power plants. With that, we can say that sulfur dioxide pollution is the main impact that power plants have.
When it reaches the atmosphere, sulfur dioxide reacts with oxygen generating sulfur trioxide, which reacts with moisture in the air and forms sulfuric acid.
As the waves progress through the medium, the particles they are made of move perpendicular to the direction in which the waves move. The particles do not move with the wave. So waves transmit energy but not matter as they progress through a medium.
