- The proportions of different gases in the atmosphereThe air around us is a mixture of gases.
- The Earth's early atmosphereThe Earth is about 4.6 billion years old, so the evidence for what the early atmosphere was like is limited.
- How oxygen increasedThere was little or no oxygen in the early atmosphere.
- How carbon dioxide decreasedThe percentage of carbon dioxide in the atmosphere decreased over time for several reasons.
- Greenhouse gasesThe Earth is warmed by the Sun.
- Human activities which contribute to an increase in greenhouse gases in the atmosphereSome human activities increase the amounts of carbon dioxide and methane in the atmosphere.
- Global climate changeGreenhouse gases keep the Earth warm, but adding more of them is a problem.
- The carbon footprint and its reductionThe carbon footprint is the total amount of carbon dioxide and other greenhouse gases given out over the full life cycle of a product, service or…
- Atmospheric pollutants from fuelsBurning fuels is a major source of atmospheric pollutants.
- Properties and effects of atmospheric pollutantsCarbon monoxide is a toxic gas.
