1.	(a) What are the causes of air pollution ?(b) Suggest five measures to prevent air pollution.
Answer» (a) When fuels bum they produce sulphur dioxide, sulphur trioxide, nitrogen dioxide, hydrogen sulphide when these gases mix with rainwater. They produce sulphuric and nitric acid. These acids mix with rain water to form acid rain. (b) Five measures for the prevention of air pollution are: 1. By using smokeless sources of energy, like solar energy and electrical energy, in place of conventional fossil fuels. 2. By using filters for the. smoke coming out of the chimneys of factories and power plants. 3. By using internal combustion engines in vehicles for the complete and efficient burning of fuel. 4. By locating industries away from residential areas. 5. By growing more trees.
