2. Causes of Air Pollution

  • Thermal power plants burning coal release sulphur dioxide, nitrogen oxides, carbon dioxide, and particulate matter.
  • Vehicles emit carbon monoxide, hydrocarbons, nitrogen oxides, and fine particulate matter, especially in urban areas.
  • Industrial activities release smoke, toxic gases, and chemical vapours.

3. Human Activities Altering Environmental Cycles

  • Human activities such as industrialisation, rapid urban growth, and intensive agriculture disturb natural environmental cycles.
  • The hydrological cycle is the continuous movement of water between the Earth's surface, atmosphere, and underground reservoirs.
  • Climate change raises evaporation and changes rainfall patterns, causing irregular precipitation, floods, and droughts.

4. Local and Global Effects of Pollution

  • Urban smog is a local example caused by vehicle emissions, industrial discharges, and construction dust.
  • Local effects of pollution include smog formation, respiratory diseases, and reduced visibility.
  • Global effects of pollution include climate change, ozone depletion, and acid rain.
