Roy Gallant has successfully synthesized science for eight to eleven year olds (and up) in a succession of books. This latest is the story of geology and geophysics, and covers a range that is perhaps beyond what one might expect. He goes back to the formation of the earth, the atmosphere, the oceans; then on to the development of geology as a science. The new findings of the under-ocean world are given their place; the formation of continents, the facts about earthquakes, about volcanoes, the building of mountains, the significance of magnetism and the poles -- all this is brought together in readable, concise form, dramatized by pictures by John Polgreen. The trade binding won't stand up to much use in libraries and schools.
