causes acid rain?
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.
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.
