Bryson tries to do what most school textbooks never manage to do, explain the context of science in a way that is relevant to the average person. At the beginning of the book, he recalls an event from his childhood when he looked at a school text and saw a cross-section of our planet. He was transfixed by it, but noticed that the book just dryly presented the facts ("This is the core." "This part is molten rock." "This is the crust.", etc.), but never really explained HOW science came to know this particular set of facts. That, he quite correctly points out, is the most interesting part. And that is story he sets out to tell in this book.
