Study Notes
Greenhouse Gases Overview
- Water vapor (H2O) is the most abundant greenhouse gas in Earth's atmosphere.
- The term "humidity" refers to water vapor present near the ground.
Greenhouse Gas Impact Factors
- The impact of a greenhouse gas is determined by its strength and abundance in the atmosphere.
Sources of Greenhouse Gases
- Human activities that produce greenhouse gases include:
- Burning fossil fuels
- Land use changes
- Livestock digestion and manure management
Major Greenhouse Gases
- The six most significant greenhouse gases include:
- Water vapor
- Carbon dioxide (CO2)
- Methane (CH4)
- Nitrous oxide (N2O)
- Ozone (O3)
- Chlorofluorocarbons (CFCs)
Natural Sources of Greenhouse Gases
- The primary natural source of greenhouse gases is volcanic eruptions.
Particulates Explained
- Particulates are airborne particles that help cool the atmosphere by offsetting warming effects of greenhouse gases.
Natural Emission of Particulates
- Sources of naturally emitted particulates include:
- Volcanic eruptions
- Dust storms
- Forest fires
- Ocean wave crashes
Human-Made Emission of Particulates
- Vehicles contribute to particulate emissions through the burning of fossil fuels, releasing toxic chemicals into the air.
Function of Particulates
- Particulates help keep heat away from Earth by reflecting solar energy.
The Good Ozone
- "Good ozone" refers to ozone located in the stratosphere, which serves as a protective layer against the sun's harmful ultraviolet rays.
