One of a series of general interest publications on science topics, the booklet provides those interested in geysers with a nontechnical introduction to the subject. Separate sections examine the nature and workings of geysers--why geysers erupt, where they occur, the cause of volcanoes and hot springs, the deep circulation of water in geyser…

Describes (1) several methods used in earthquake research, including P:S ratio velocity studies, dilatancy models; and (2) techniques for gathering base-line data for prediction using seismographs, tiltmeters, laser beams, magnetic field changes, folklore, animal behavior. The mysterious Palmdale (California) bulge is discussed. (CS)

Discusses economic, social and political consequences of earthquake prediction. Reviews impact of prediction on China's recent (February, 1975) earthquake. Diagrams a chain of likely economic consequences from predicting an earthquake. (CS)

Discusses ways in which a taffy candy bar can be used to illustrate, by analogy, deformations of the earth's crust under compressive stress. (MLH)

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…

Describes a laboratory exercise testing the Vine-Matthews-Morley hypothesis of plate tectonics. Includes 14 questions with explanations using graphs and charts. Provides a historical account of the current plate tectonic and magnetic anomaly theory. (MVL)

Develops an exercise in which students use magnetic-profile data gathered in the South Pacific to test the Vine-Matthews-Morley hypothesis. Uses the Eltanin 19N and 20N profiles. Relates the exercise to 20 current geology texts. (MVL)

Suggested are methods for the collection of field evidence about processes that form plutonic and metamorphic rock. Description and discussion of these types of rocks are provided. The planning and execution of a successful field trip is discussed. Advanced field projects are also discussed. Included are five appendices, references, and a…
