C11 - greenhouse gases Flashcards
Name 3 greenhouse gases?
Carbon dioxide
Methane
Water vapour
What causes less carbon dioxide to be removed from the air?
Deforestation. More trees cut down for timber and land = less CO2 removed from the air = photosynthesis is reduced
What makes the oceans less effective?
Temperature rises = CO2 less soluble in water = makes oceans less effective because ‘CO2 sinks’
Why is there an increase in methane in the air?
More animal farming = more emissions and decomposing waste
Increased waste so more decomposition in landfill sites
Effects of global climate change?
- Frequent and severe storms
- Changes in temperature and distribution of rainfall
- Rising sea levels = melting ice caps = flooding
Difference between portable water and pure water?
Portable water: contains dissolved impurities
Pure water: High level of salts and microbes = dangerous for humans to drink
What is a formulation?
Mixture that has been designed to do something useful. Formed by mixing together several different substances in carefully measured quantities
