FOSS Science Resources Book Errata
Some printings may contain the following errors.
Page 231, Third Sentence
In printings 1-4, this sentence states:
"When warm air over the land runs into a mass of cold air, the warm air is forced upward violently."
It should read:
"When cold air over the land runs into a mass of warm air, the warm air is forced upward violently."
This correction was made in printing 5.
