Comment on this resource
Appalachian Mountain landforms clearly demonstrate the relation of plate tectonics and structure to geomorphology. The folded rocks record the convergence of two continental plates in Pennsylvanian/Permian time. This page uses text, maps, and remotely sensed imagery to explain the relationship between plate tectonics, geologic structures, and the resulting landforms. It is part of an out-of-print ...

This is a brief review of the role of polar reversals in the development of the Theory of Plate Tectonics from the old continental drift concept of Alfred Wegener. It describes the physical difference between the continents and the ocean floor and also the surprising order of the magnetic bands on the ocean floor and how this led to the idea of sea-floor spreading as postulated by Fred Vines and Drummond ...

This teacher's guide and activity uses a paper model to teach students about sea-floor spreading and the evolution of oceanic crust. It includes background information for teachers about plate boundaries, ocean floor features, and Earth's magnetic field, as well as procedures, materials needed, and discussion questions.

This interactive site uses illustrations and photographs along with text to explain the movement of tectonic plates and the result of this movement on the surface of the Earth. There is a detailed discussion of the movement at each of the four types of plate boundaries: divergent, convergent, transform, and plate boundary zones. Both lateral and vertical movements are depicted by maps and diagrams ... Full description.

This background information on Alfred Wegener discusses his idea of continental drift. It explains how he came to the conclusion that the continents split apart as outlined in his 1915 book The Origin of Continents and Oceans. The site also provides information about his death in 1930 only a year after the final revision of his book. Full description.

This unit introduces students to the development of the theory of continental drift. They will examine the early work of Alfred Wegener and Alexander DuToit, investigate lines of evidence that resulted in the development of the theory, and learn about the final lines of evidence that resulted in the theory's acceptance. There is a set of activities in which the students construct a map of Pangea using ... Full description.

In this activity students will become familiar with oceanography terms by writing an oceanography horror story. Terms include sea floor features, marine organisms, oceanographic sampling, and creative writing. Students can use their imaginations to good advantage in this activity, but they must get the facts right! For example, they can change one characteristic of an organism, such as increasing ...

This activity helps students understand why compass angles need to be corrected for regional magnetic variation. The magnetic compass, perfected slowly over years of experimentation, trial, and scientific endeavor, became the sailor's most common and most reliable direction-indicating aid, but is influenced by magnetic variabilities and the location of magnetic north. Terms introduced include compass, ... Full description.

In this lesson, students work in teams to build models of ocean floor topography, which they exchange with other teams. Each team then plans and performs measurements of their models to map the sea floor, which is concealed by covering the box or adding water to cover the features. The lesson provides an introduction to bathymetry (ocean floor topography) and to the use of remote measuring methods ... Full description.
