On Solid Ground

On Solid Ground illustrates what geologists know about the earth by telling the stories of the people who made major geological discoveries. It also chronicles the doubters and nay-sayers who have worked so hard to undermine our understanding of the earth. Each chapter of this book contains three things: the human story of a geologic controversy, an explanation of why geologists are so sure about the right answer to that controversy, and a short discussion of the logical fallacies being used by those still unwilling to accept geologic expertise.
