Continental margins are an important part of the ocean floor. They separate the land above sea level from the deep ocean basins below and occupy about 11% of Earth's surface. They are also economically important, as they harbor both mineral resources and some of the most valuable fisheries in the world. In this article students investigate North…

In 1990, a group of geologists discovered a large number of shatter cones in southwestern Montana. Shatter cones are a type of metamorphosed rock often found in impact structures (the remains of a crater after a meteor impact and years of Earth activity). Scientists have discovered only 168 impact craters around the world. If rocks could talk,…

Discussed are field analyses of data involving paleocurrent directions using a goniometer and special programs for a pocket computer. States that on-site evaluation can provide immediate realization and verification of anomalous results. Includes computer programs and directions for building a goniometer. (CW)

Discussed is a program created to serve as an instructional tool for teaching basin analysis. Described is the use of the program for interpreting plots resulting from backstripping methods. Included in the discussion are implementation, applications and availability of the "Subside!" program. (CW)

This monograph attempts to show the importance of bringing marine biology into science classrooms, discusses what makes the ocean so important and explains why oceanography should be included in the science curriculum regardless of where students live. Section I, "Getting Started," includes discussions on the following: (1) "Why…

Described is a simulation program designed to teach the geology of oil exploration in a game format. Discussed are information and tools provided, information management, data sets, and availability of the program. (CW)

Describes the author's computer-based program for a subduction-zone-earthquake exercise. Instructions for conducting the activity and obtaining the program from the author are provided. Written in IBM QuickBasic. (PR)
