This book traces the history of objections raised to the theory of plate tectonics, starting in the late 1960s. A surprising number of professional geologists and geophysicists raised legitimate concerns about the theory at the time it was proposed in the 1960s. Little was known about the ocean floor at that time. As more data has become available, it has become apparent that the theory has major issues. Twenty of these issues are described in detail in this book, and fifteen additional problems are mentioned briefly. The "insider scoop" is revealed, answering the question of why so many geologists support the theory if it has so many problems. Finally, the book gives summaries of four other theories that explain the earth's geological features without using plate tectonics.
