This site contains 25 questions on the topic of plate tectonics, which covers the development of the theory, crustal movements, geologic features associated with tectonics, and plate boundaries (convergent, divergent, transform). This is part of the Principles of Earth Science course at the University of South Dakota. Users submit their answers and are provided immediate verification. Full description.

This article profiles Harry Hess, who is known as one of the truly remarkable Earth scientists of the 20th century. It describes the historical background of continental drift, ideas upon which his theories were built. The site goes on to discuss the work of Hess as a World War Two naval commander, during which he developed a system for estimating the daily position of German submarines and discovered ...

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 site provides information on plate boundaries, which are found at the edge of the lithospheric plates and are of three types: convergent, divergent and conservative. Wide zones of deformation are usually characteristic of plate boundaries because of the interaction between two plates. The three boundaries are characterized by their distinct motions which are described in the text and depicted ... Full description.

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 ...

In this activity students use maps of the positions of the continents over the past 180 million years, and, with some basic concepts about climate zones, hypothesize what climate changes may have occurred due to plate movements. They will discover that even though climate zones are oriented roughly parallel to lines of latitude about the Earth, according to the theory of plate tectonics, the continents ... Full description.

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.
