Intended as a supplement to undergraduate college geography courses, this resource paper describes the science of geomorphology, the study of landforms. The general aim of this paper is to review the developments which have made geomorphology what it is today, to indicate its present character and status, to demonstrate its increasingly close…

Intended to supplement undergraduate college geography courses, this resource paper investigates several concepts which are prerequisite to the study of physical geography. The student is provided with a "systems" approach to physical geography, which combines the underlying principles of physics with the contextual application of these principles…

Intended as a supplement to undergraduate college geography courses, this resource paper reviews the mechanism by which surface weather features are linked with the mid-atmospheric circulation within the westerly wind belt. Specifically, vertical atmospheric motions associated with certain aspects of the upper tropospheric flow, including jet…

This booklet is designed to assist teachers in their use of overhead projectors when teaching geography. With the overhead technique, relationships among patterns can be suggested bit by bit on inexpensive, easily prepared overlays that are projected to sizes appropriate for a particular instructional situation. A general discussion of the…
