This handy reference is the perfect takealong for any study of earth science. From the geological forces that create rocks to related topics such as erosion and weathering, fossils, human uses, and rocks from space, this is a thorough look at one of the fundamental areas of natural science.
Pretty pictures (my almost-three-year-old daughter was especially impressed with the volcanoes, and warned me not to burn myself), but I found a couple inconsistencies in the text that make me wonder about its accuracy overall. I would have liked it if they had illustrated/described some of the processes on a molecular level. I found the presentation of the content too superficial.
