Plate tectonics is now almost universally accepted, its mechanisms plausible and to a degree demonstrable. However, many details of the mechanism are yet to be worked out, and many theories involving various details of plate tectonics rest on some questionable assumptions. This set of pages attempts to define some of the basic principles of the mechanism, and to examine their effect on the creation of landforms.
What follows is NOT a summary of the current thinking about plate tectonics and its mechanisms; rather, many new, and probably highly controversial, ideas are presented for consideration. What IS presented is a broad analysis of the basic principles that should apply to the movements of plates, some new hypotheses about how they apply to convection and landform formation, and some expected scenarios for differing tectonic events.
For those unfamiliar with the theory of plate tectonics, a separate page - The Basics of Plate Tectonics - is provided. This summary offers a brief condensation of the basic principles of Plate Tectonics. A much more comprehensive explanation of Plate Tectonics can be found on the USGS Web Site.
