Atmosphere, weather, oceanography, earthquakes, volcanoes, rocks, and fossils are just some of the earth-science topics of this outstanding text. The geology section includes a good refutation of the "principle of uniformity" and other ideas of evolutionary philosophers. Basic concepts of chemistry are presented in a simple and yet accurate manner, and physics concepts are applied to lasers, computers, and other electronic devices.
NOTE: This is a discontinued item from Abeka. This set includes the text book and the answer key (from Christian Liberty), which includes the text answers (End of chapter questions) and the tests key. The test key has some light pencil marks, otherwise both books still in really good condition.
