The document discusses the causes and effects of acid rain and deforestation, focusing on their environmental impacts. Acid rain, resulting from sulfur dioxide and nitrogen oxides emissions, poses risks to health and infrastructure, while deforestation significantly contributes to global warming and biodiversity loss. The text emphasizes the need to address both issues to mitigate their adverse effects on ecosystems and human health.

3. How Acid RainWorksAcid rain occurs mostly in the Northern Hemisphere Acid rain, also known as acid deposition, is caused by emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx)from power plants, cars and factories. SO2 / NOx + H2O-> H2SO4 / HNO3

4. The pH of Acid RainExpress the acidity of acid rain using the pH scale. The scale defines a solution's acidity, neutrality or alkalinity based on its concentration of hydrogen ions. ( 0 – 14 pH)Acids – pH > 7,0Most life is comfortable at a near- neutral pH (7,0

5. The pH of Acid RainAcidrain - pH of 5.0 orless. Mostaciddeposition ranges from pH 4.3 to 5.0

8. The Effects of Acid RainEffects for our healthSulfate (SO4), nitrate (NO3) particulates of dry deposition can ­cause asthma, bronchitis and heart problems. The NOx in acid deposition also reacts with volatile organic compounds (VOCs) to form ground-level ozone (O3). Ozone, or smog, aggravates and weakens the respiratory system.
