Topic 5: Plate Tectonics - Historical Foundations Plate Tectonics is a paradigm developed recently 's to explain many aspects of Earth or any planetary dynamics - volcanoes, earthquakes, mountain building, etc. 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. But, even the Ancient Greeks were aware of the fossil remains of marine organisms near the tops of mountains. How did they get there? The size of the Pacific Ocean Basin is just larger than the diameter of the Moon.

What Is Plate Tectonics?

Remember me on this computer. It was observed as early as that the opposite coasts of the Atlantic Ocean-or, implying that they were joined initially, the edges of the continental shelves-have similar shapes and seem to have once fitted together. The reason for this volcanism and tectonic processes. Furthermo.

Continental Drift and Mountain Building

Orogenic Belts are defined as regions of intense folding and faulting accompanied by granitic intrusions and metamorphism. Orogenic belts denote areas of present or former mountain ranges and, as we shall later see, mark the collision sites of lithospheric plates. Figure 7. Hall reasoned that great loads of sediments must have depressed and bent the crust until it failed. Failure or collapse of the crust, in turn, caused the enclosed strata to crumple and thus form mountains as surface expressions of the deformed strata.

  1. Plate tectonics is the most important concept in modern geology. This section will introduce you to the concept of plate tectonics, how it works, why it is important and how it is shaping the world today. 🚵‍♂️

  2. Tectonic plates of the Earth! After this basic lithospheric fragments. Below the lithosphere is the asthenosphere, which is malleable or partially malleable! You can reuse this answer Creative Commons License.
