One of a series of general interest publications on science topics, this booklet provides a non-technical introduction to the subject of volcanoes. Separate sections examine the nature and workings of volcanoes, types of volcanoes, volcanic geological structures such as plugs and maars, types of eruptions, volcanic-related activity such as geysers…

Traces the history of various theories about Mars that were derived through direct observation. (MLH)

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 the physical aspects of Mars, including old and new theories. Discusses the proposed landing sites of Viking. (MLH)

Reviews the basic principles and methods of nuclear chronalogy or radiometric dating. Includes rubidium-strontium dating, radiocarbon dating, and an outline of recent findings. (MLH)

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)

Presents an annotated bibliography of books, journals, and films on various subtopics of geophysics, including geodesy, seismology, granity, geomagnetism, geochronalogy, and plate tectonics. (MLH)

One of a series of general interest publications on science topics, the booklet provides those interested in earthquakes with an introduction to the subject. Following a section presenting an historical look at the world's major earthquakes, the booklet discusses earthquake-prone geographic areas, the nature and workings of earthquakes, earthquake…

Describes petroleum exploration techniques, particularly the interpretation of seismograms. (CP)

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)

Describes the operation principles, construction, and accessories of a land or survey gyrocompass. Indicates an agreement within O.1 degree in the direct comparison of the gyro-north with the astronomic north. (CC)

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)

The resources listed different types of materials related to the aerospace science under specified categories: free materials and inexpensive, selected government publication, audiovisual (government, nongovernment), aviation books, and space books. The list includes the publisher's name and the price for each publication. (SK)

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…
