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

Instructional module focusing on the development of plate tectonic theory. Discussion includes the evidence of Pangaea, and the processes of seafloor topography and seafloor spreading. Site also includes an interactive practice quiz and...

This site contains an in-depth explanation of the causes of earthquakes as they relate to plate tectonics, and also has many nice and easy to read pictures, maps, and diagrams of plate tectonics and earthquakes.

[Free Registration/Login may be required to access all resource tools.] Summarizes the key points about three theories in Earth Science: the theory of evolution, the theory of plate tectonics, and the theory of climate change due to...

This interactive activity produced for Teachers' Domain shows the relationship between tectonic boundaries and the locations of earthquake events and volcanoes around the world.

With its clickable map, this site provides text and graphics on spreading boundary, converging boundary, subduction zone, transverse boundaries and faults.

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).

Complete biographical information with links to his theories. Contains links to interactives on plate tectonics.

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