Assignment 7 - “Earth’s Atmosphere” Comprehension and Review Questions
Answer all of the following questions to the best of your ability in complete sentences in the space below or on a piece of looseleaf.
1. Explain how Earth’s atmosphere is conducive to complex life (as we know it).
2. Explain, in your own words, why and how air moves on Earth.
3. Compare and contrast Earth’s current atmosphere to that of Mars and Venus.
4. MATH FUN – The mass of Earth’s atmosphere is 5.15 x 1018 kg. The atmosphere is 78% nitrogen, 21% oxygen, and 1% argon. Use that information to estimate the total atmospheric mass of each of those components. Show your work and DO NOT USE A CALCULATOR.
Here’s how to start… round the mass of Earth’s atmosphere to 5 x 1018 kg. Then think about nitrogen as 80% of Earth’s atmosphere, oxygen as 20%, and argon as 1% (shhh…. don't think about it too much).
