This book uses all kinds of insights from mineralogy and seismology to put together a picture of what the Earth’s composed of, layer by layer. Despite the author’s obvious enthusiasm, this isn’t one of my primary interests, and I did find my interest flagging at times — it seemed like some chapters were just unnecessarily dragged out and like he got off the point some of the time. Nonetheless, if this is the kind of science that enthuses you, it’s worth reading — it deals with the history of the study of our Earth as well as the straightforward facts about the composition of each layer.
The more I learn about all kinds of science, including Earth science, the happier I am. Even if it’s not my field, I’m glad I read this.
