Study Notes
Composition of Earth's Atmosphere
- Nitrogen (N2) makes up the largest percentage of Earth's atmosphere.
- Oxygen (O2) is the second most abundant gas in Earth's atmosphere.
- Neon (Ne) is present in the smallest amount in Earth's atmosphere.
Early Earth's Atmosphere
- During the early stages of Earth's history, volcanic activity mainly produced carbon dioxide (CO2).
Reduction of Carbon Dioxide
- The process of photosynthesis reduced the abundance of carbon dioxide in Earth's atmosphere.
Earth's Atmosphere
- The term "atmosphere" refers to the protective layer of gases surrounding the Earth.
- The main function of the Earth's atmosphere is to regulate temperature and maintain life on Earth.
Energy and Heat
- Most of the sun's heat energy that reaches the Earth's surface is absorbed and re-radiated by the atmosphere and the Earth's surface.
Global Warming and Climate Change
- Global warming refers to the increase in the average temperature of the Earth's atmosphere.
- Climate change refers to the long-term alteration of the Earth's climate, which includes warming, but also other changes such as shifts in precipitation patterns.
- The consequences of global warming and climate change could include rising sea levels, more frequent and severe weather events, and disruptions to ecosystems and human societies.
