Abstract
The theory of plate tectonics is now so widely accepted that it may come as a surprise to discover that some scientists remain unconvinced. Several of those scientists have produced a book explaining their concerns. The book is a compilation of 23 papers, most of which are critical of plate tectonics theory, although all the authors accept the premise that Earth's surface has a long, dynamic history. Alternative models favored by various authors include a "rapidly" expanding Earth, a "slowly" expanding Earth, a contracting Earth, and a model called "surge tectonics."
