Question : Normal rain is slightly acidic because it has absorbed some carbon dioxide from the air.
Acid rain is more acidic than normal rain because it has absorbed gases like sulphur oxides and nitrogen oxides as well.
Where do these sulphur oxides and nitrogen oxides in the air come from?
Answer :  Responses that mention any one of: car exhausts, factory emissions, burning fossil fuels such as oil and coal, gases from volcanoes or other similar things.
Burning coal and gas. Oxides in the air come from pollution from factories and industries.
Volcanoes. Fumes from power plants.
They come from the burning of materials that contain sulfur and nitrogen.
– Responses that include an incorrect as well as a correct source of the pollution.
Fossil fuel and nuclear power plants. [Nuclear power plants are not a source of acid rain.]
The oxides come from the ozone, atmosphere and meteors coming toward Earth.
Also, the burning of fossil fuels.
– Responses that refer to “pollution” but do not give a source of pollution that is a significant cause of acid rain.
Pollution.
The environment in general, the atmosphere we live in – e.g., pollution.
Gasification, pollution, fires, cigarettes.
Pollution such as from nuclear power plants.

Question : The effect of acid rain on marble can be modelled by placing chips of marble in vinegar overnight. Vinegar and acid rain have about the same acidity level.
