Atmosphere Notes

This week's experiment focused on the composition of Earth's atmosphere, revealing that it consists of 78% nitrogen, 21% oxygen, 0.9% argon, and 0.1% other gases (including CO2). We learned about greenhouse gases, which absorb and retain heat, with the top three being water vapor, carbon dioxide (CO2), and methane. We compared Earth's atmosphere to those of Venus and Mars, noting that Venus is much hotter due to its dense CO2 atmosphere, while Mars, with its thin atmosphere, experiences temperature extremes.

Presentation Transcript

  1. Atmosphere Notes

  2. Composition • Our Experiment this week helped support what scientist study about what our atmosphere is made of: • NITROGEN 78 % • OXYGEN 21 % • Argon 0.9 % • Other 0.1% (Other includes CO2) Draw this in the circle on your notes

  3. OTHER Gases: Greenhouse Gases

  4. GREENHOUSE GASES trap and absorb heat from the sun into the atmosphere.

  5. Greenhouse Gases • The Top 3 Greenhouse gases are: • Water Vapor (Water in Gas form) • Carbon Dioxide (CO2) • Methane

  6. CO2 Increase since 1960

  7. Change in temperature by 1995-2004

  8. Atmosphere of Venus • Venus has about as much gas as Earth. • Venus’s atmosphere is made mostly of CO2 (95%) • Is this hotter or colder than earth? Holds in much more heat than it gives off, so much hotter than earth.

  9. Atmosphere of Mars • Mars has same amount of Sun exposure as Earth. • Mars has much thinner atmosphere than Earth. Thin atmosphere mostly made of CO2. • Would this be Hotter or Colder than Earth?

  10. Atmosphere of Mars Hotter during the day, colder nights. Because little atmosphere to protect, but also little atmosphere to hold in heat.
