organization on elementary topics (landforms, rocks, minerals), it integrates current thinking on processes (plate techtonics, chemical cycles, changes throughout geologic time).

Treatments on climate, paleoclimatology and landscape evolution are unique to this book, as is the depth of discussion on how greatly human activity affects geological interactions.
