Maps and diagrams help illustrate the geological processes and clarify scientific concepts. Fact-filled, curious, and way more fun than the geology you remember from grade school, Aerial Geology is a must-have for the insatiably curious, armchair geologists, million-mile travelers, and anyone who has stared out the window of a plane and wondered what was below.
