We describe a simple experiment demonstrating the variation in magnitude of a magnetic field with distance. The method described requires only an ordinary magnetic compass and a permanent magnet. The proposed graphical analysis illustrates a unique method for deducing a general rule of magnetostatics. (Contains 1 table and 6 figures.)

Describes the Alpha Centauri star system, which is the closest star system to the sun. Discusses the difficulties associated with measurements involving Alpha Centauri, along with some of the recent advances in stellar seismology. Raises questions about the possibilities of planets around Alpha Centauri. (TW)

Described are concepts involved with the formation and actions of the Mid-Ocean Ridge. Sea-floor spreading, the magma supply model, discontinuities, off-axis structures, overlaps and deviation, and aquatic life are discussed. (CW)

Described is the use of a microcomputer and computer software to simulate the use of geological equipment. The technique uses pictures of the control panel (with switches and dials that can be activated) and a story board that can provide the simulation. A simple seismograph is used as an example of possible simulations. (RH)

Discussed are some of the reasons for earthquakes which occur in stable crust away from familiar zones at the ends of tectonic plates. Crust stability and the reactivation of old faults are described using examples from India and Australia. (CW)

Presented in table format are student enrollment data for geoscience disciplines at colleges and universities in the United States and Canada. Subfields for both countries include: geology; geophysics; oceanography; marine science; geological engineering; geophysical engineering; geochemistry; hydrology; mineralogy; paleontology; soil science;…
