The most common igneous minerals and their diagnostic properties, which the author considers the most significant and pragmatic aspect of igneous geology for physical geography students, are discussed. The nature of igneous geology is also examined. (RM)

Presents and discusses a photograph showing the changing shoreline of Cape Hatteras. (RM)

This discussion of weather models uses maps to illustrate the differences among three types of frontal cyclones (long wave, short wave, and troughs). Awareness of these cyclones can provide clues to atmospheric conditions which can lead toward accurate weather forecasting. (AM)

The promotion of education for sustainable development (ESD) is likely to be constrained by its compatibility with other missions and objectives of higher education institutions (HEIs). Finding space for ESD in the Enterprise Economy invites consideration of opportunities for increasing the visibility and audibility of environmental messages in HE…

A field and laboratory exercise for an undergraduate geomorphology class is described that focuses on the beach. The project requires one day of fieldwork and two laboratory sessions. In the field, students measure water surface fluctuations (waves) with a pressure sensor, survey beach profiles, collect sediment samples, and observe the beach…

This paper explores the uses of true landform miniatures and small-scale analogues and suggests ways to teach geomorphological concepts using small-scale relief features as illustrative examples. (JDH)

Within this huge national park (over two million acres spread across Wyoming, Montana, and Idaho) are steaming geysers, hot springs, bubbling mudpots, and fumaroles, or steam vents. Drives on the main roads of Yellowstone take tourists through the major hot attractions, which also include Norris Geyser Basin, Upper and Lower Geyser Basin, West…

One of a series of general interest publications on science topics, the booklet provides those interested in the study of caves (speleology) with a nontechnical introduction to the subject. Separate sections examine types of caves, how caves form, cave features, minerals found in caves, uses of caves, and caves as natural underground laboratories.…

The purpose of this paper is to briefly explore some of the questions with which this and the next generation will be faced concerning the wise and equitable use of ocean space and seabed minerals and to look at contemporary efforts to resolve some of these questions. (Author)

A new seismic risk map of the United States is presented, along with strain release and maximum Modified Mercalli intesity maps of the country. Frequency of occurrence of damaging earthquakes was not considered in zone ratings, but included frequency studies may aid interpretation. Discussion of methods is included with review of calculations. (MH)

Probes the intellectual and philosophical roots of geography. Devotes particular attention to the relationship between geography and the academic world and the emergence of topical specializations within the field. Offers a new graphic representation of the geography specializations which shows a more unified view of the field. (JDH)

The historical destinies of all nations have been strongly conditioned by their geographic setting and their natural environment. Intended as background information for teachers, geographical features of the USSR are discussed. (RM)

The synthesis of two approaches that can be used in teaching geomorphology is described. The equilibrium approach explains landforms and landform change in terms of equilibrium between landforms and controlling processes. The historical approach draws on climatic geomorphology to describe the effects of Quaternary climatic and tectonic events on…

Presents a photograph of the Hawaiian island, Oahu, as taken by the Landsat 2 satellite on February 14, 1978. A description of Landsat 2 remote sensing procedures and discussion of the topographical details shown in the photograph are included. (AM)
