The Theory of Plate Tectonics | Geology

Plate tectonic is newer form of Continental drift with more evidence and an proposed mechanism for the movement of the Continents. Continental drift was rejected at the time it was proposed despite substantial evidence to support the theory. The rejection was based on several factors. Continental drift challenged the prevailing theories of uniform processes, and the geosyncline theory of mountain building. The evidence for Continental drift indicated that the Continents had separated at timeline that went against the proposed evolutionary timeline for the fossil record. Most telling there was no proposed mechanism for what force could move the massive continents.

Evolution of Views about the Origin of the Ocean Basins Before the 19th Century AD, the most common view was that all Earth features formed during the origin of planet and are mostly unchanged since then. The lithosphere is divided into a dozen major and several minor plates figure 2. A chapter devoted to the relationship between aspects of plate tectonism have been presented and the mountain building and plate tectonics is followed by an book follows a logical set of chapters to explain specific introduction to old orogens; this logical linking together geotectonic situations.
