The Seventh Edition of this classroom-tested laboratory manual retains the flexibility and scope that have made faculty adopt it for their courses for close to five decades. The new author team of Ritter and Petersen (formerly Petersen and Rigby) has carefully reviewed the topics covered in historical geology courses and tailored the exercises to reflect those subjects. The authors provide students the opportunity to work with geological data from a variety of sources and scales such as rocks, fossils, and maps. While the book's size and approach remain true to previous editions, the content of the latest edition has been reorganized into logical groupings, offering theme-based exercises on such topics as mountain-building and Pleistocene glaciation. Students will appreciate the new illustrations added throughout the book that make the assignments clearer and more straightforward.
