Summary of Reviews
Reviewer: Carrie Morrill
Comments: The explanation of the greenhouse effect is one of the most accurate I've read in educational resources. One exception is the sentence: "When the light reflects off Earth's surface, it is transformed to longwave radiation." This is incorrect, reflected light is still shortwave radiation. Longwave radiation is produced when the Earth's surface absorbs shortwave and emits longwave.

Comments: Working on a 56k modem makes this site incredibly frustrating. I had to download both Quicktime and Shockwave, and the wait time for that coupled with the wait time for downloading each movie is not good. On a system with a fast server this would be a great site. A good teachers guide. Gives terms, descriptions, and time estimates.
