Study Notes
Earth's Atmosphere and Sun
- The Earth's distance from the sun enables it to receive the necessary heat and light, making life on the planet possible.
Atmospheric Composition
- Nitrogen makes up approximately 78% of Earth's atmosphere.
Ozone Layer
- The ozone layer's primary purpose is to protect life on Earth by absorbing harmful ultraviolet (UV) radiation from the sun.
- The main function of the ozone layer is to shield Earth from damaging UV radiation.
Importance of Atmosphere
- Earth's atmosphere is crucial for sustaining life, as it provides the necessary conditions for life to thrive.
Consequences of Change
- If Earth were farther away from the sun, the planet would be much colder, making life as we know it impossible.
- Without an ozone layer, Earth's atmosphere would be exposed to harmful UV radiation, posing a significant threat to life on the planet.
Energy and Life
- The sun's energy is responsible for generating weather patterns, warming the oceans, and stirring the atmosphere, ultimately providing radiant energy for plants to produce their own food through photosynthesis.
Atmospheric Gases
- Carbon dioxide makes up approximately 1% of Earth's atmosphere.
Uniqueness of Earth
- Earth is the only planet in the solar system capable of supporting life due to its unique combination of atmospheric conditions and distance from the sun.
