Chemistry of The Atmosphere

Cards (22)

  • What has changed over the course of Earth's history in atmospheric chemistry?
    The composition of gases in the atmosphere
  • Why do we need to extrapolate to understand past atmospheric conditions?
    Because historical records are limited
  • What was likely the primary gas in the early atmosphere?
    Nitrogen and carbon dioxide
  • How did carbon dioxide likely dissolve in the oceans?
    From water vapor condensing from volcanoes
  • What can trap carbon dioxide in the geological record?
    Sediment rocks and fossil fuels
  • What process do algae and plants use to convert CO2 into oxygen?
    Photosynthesis
  • What is the current level of CO2 in the atmosphere?
    0.018%
  • What gases absorb longer wavelength radiation to keep the Earth warm?
    Water vapor, carbon dioxide, and methane
  • What is the greenhouse effect?
    It keeps the Earth warm by trapping heat
  • How have CO2 levels changed since the Industrial Revolution?
    They have increased significantly
  • What percentage of the greenhouse effect is caused by water vapor?
    95%
  • What does the AQA specification say about modeling complex systems?
    It's incredibly hard to model them
  • What has been the trend of IPCC models over the last 20 years?
    They have been wildly incorrect
  • What was the public reaction to the term "carbon footprint" in the mid-2000s?
    People became very concerned about it
  • What is carbon monoxide and why is it dangerous?
    It binds to red blood cells, reducing oxygen transport
  • What are the characteristics of carbon monoxide?
    Odorless and colorless
  • What pollutant is released when fossil fuels are burned?
    Sulfur dioxide
  • What environmental issue is caused by sulfur dioxide?
    Acid rain
  • What health problems can nitrogen oxides cause?
    Breathing problems
  • What is particulate carbon and how is it formed?
    It is made from incomplete combustion
  • What health issues can particulate carbon cause?
    It can cause various health issues
  • What are the main components of atmospheric chemistry discussed?
    • Composition of gases in the atmosphere
    • Historical changes in gas levels
    • Role of photosynthesis in oxygen production
    • Greenhouse gases and their effects
    • Impact of pollutants on health and environment
