1. Problems of Burning Fossil Fuels: ACID RAIN

3. The Formation of Acid Rain Burning fossil fuels in Transport, Industry, Homes, power stations produces sulpur dioxide and nitrogen oxide. These chemicals rise into the atmosphere and react with sunlight and ozone in the atmosphere; nitric and sulphuric acid are produced Gas, Oil, Coal Some falls back to Earth close to the source as dry particles, gas and aerosols (dry deposition) Some is dissolved in the moisture in the atmosphere making and can be carried large distances before falling as rain or snow (wet deposition)

4. Why is acid rain an international issue?

6. Consequences of Acid Rain Acids activate aluminium from the soil which leaches into water and fish die. Drinking water is contaminated This stand of trees near Most, Czech Republic, has completely died. Buildings and precious stone objects are weathered away as the stone reacts with the acid When soil is contaminated, cereal (arable) production drops

7. How can acid rain be managed? gas flue desulfurization (water is sprayed down the chimneys and this turns the gases to sulfuric and nitric acids) construct taller chimneys use less energy more efficiently fluidized bed technology (limestone is burnt with the coal so that the sulfur remains with the limestone) burn coal that contains less sulfur use more nuclear or renewable energy
