Post #12

Acid rain is caused by the burning of fossil fuels. Burning oil, gas and coal in power stations releases Sulphur Dioxide (SO2) into the atmosphere. Burning oil and petrol in motor vehicles puts nitrogen oxides (NOX) into the atmosphere.
These gases mix with water droplets in the atmosphere creating weak solutions of nitric and sulphuric acids. When precipitation occurs these solutions fall as acid rain.
