100

Describe freshwater distribution.



  • Majority in ice caps
  • Some groundwater
  • Very little accessible


100

Describe atmospheric composition.



  • Nitrogen (~78%)
  • Oxygen (~21%)
  • Trace gases


100

 Describe causes of climate change.



  • Fossil fuel burning
  • Deforestation
  • Industrial activity


200

Explain causes of water scarcity.



  • Climate change
  • Overuse
  • Population growth
  • Pollution


200

Explain causes of air pollution.



  • Burning fossil fuels
  • Vehicle emissions
  • Industrial processes


200

Explain enhanced greenhouse effect.



  • More greenhouse gases
  • More heat trapped
  • Leads to warming


300

Discuss desalination pros and cons.



  • Pros: reliable supply, reduces scarcity
  • Cons: expensive, high energy use, environmental impact


300

Discuss acid rain formation and impacts.



  • SO₂ and NOx react with water
  • Damages plants and soil
  • Harms aquatic life


300

Discuss impacts of climate change.



  • Sea level rise
  • Extreme weather
  • Habitat loss
  • Food insecurity


400

Analyze impacts of dams.



  • Flooding habitats
  • Displacing people
  • Changing ecosystems


400

Analyze greenhouse gases’ role.



  • Trap heat
  • Maintain temperature
  • Excess leads to warming


400

Analyze mitigation vs adaptation.



  • Mitigation reduces emissions
  • Adaptation reduces impacts
  • Both needed for effectiveness


500

Evaluate water management strategies.



  • Recycling = sustainable
  • Conservation reduces demand
  • Dams/desalination have impacts
  • Effectiveness depends on region


500

Evaluate policies to reduce air pollution.



  • Laws limit emissions
  • Technology reduces pollution
  • Enforcement varies
  • Economic costs affect success


500

Evaluate challenges of global cooperation.



  • Economic differences
  • Political disagreements
  • Unequal responsibility
  • Lack of enforcement
