A detailed discussion of plate tectonics. Looks at continental drift, types of tectonic plates and plate boundaries, and primary and secondary tectonic plates.

The theory of plate tectonics revolutionized geology in the 1960's. In this project you can explore the connection between plate tectonics and earthquakes by mapping historical seismic data.

Provides a good overview of plate tectonics with embedded links to related information.

A webpage explaining the main features of plate tectonics. Understand what evidence exists for plate tectonics and the theory of Pangea. Also learn about the different types of boundaries. The end of the webpage includes more links that...

Explains what is meant by the Theory of Continental Drift, its earliest proponents, the stages of continental drift, the causes related to tectonic plate movement, the evidence that has been found, and how the Himalaya Mountains offer...

This resource gives an introduction to the theory of plate tectonics. It also has animations of four types of plate boundary interactions (convergent, divergent, transforming, collisional).

Find out about the life and work of Alfred Wegener, known for his achievements in meteorology and as a pioneer of polar research, and is most remembered as the originator of the theory of continental drift.

Two biographies of Wegener and his work including his theory on how raindrops form.
