This Strahler exercise manual contains over 100 exercises and is cross-referenced to Elements of Physical Geography, Fourth Edition and Modern Physical Gerography. Provides coverage of major text chapters and topics as it emphasizes problem-solving activities that inculcate the scientific method of research. Most exercises require students to analyze and process data from nature to reveal processes of origin and change. New introductory material relates each topic to significant and familiar aspects of everyday life, and also includes references to current events and environmental problems. Geographical relationships are stressed throughout, requiring students to locate on world maps the physical and cultural features referred to in the questions. Tables, graphs, maps and photos are contained within the manual or main text.
