Literacy Requirements
There is a significant writing requirement for
this course. Homework and course project.
There is also a science literacy requirement for
this course. This means that we:
• Use scientific notation for writing numbers
(especially rather large or small ones).
• Specify units of physical quantities
(e.g. meters for elevation, etc.).
• Attempt to quantify physical relationships.

Importance of Atmosphere
• Point 1- Offers Protection
Consider surface temperatures
Without atmosphere?
o
0 F average, large day-night swings
Similar to the Moon’s Climate
With atmosphere…
o
60 F average, moderate diurnal swings
