The First Exponential Reason Supporting The Theory Of Plate Tectonics

Plate tectonics is a scientific theory that describes the large-scale motion of Earth’s Lithosphere. The theory was believed to be developed around 1912 by Alfred Wegener. Wegener introduced the fact that all of today’s continents were once a large supercontinent (Pangea) and how they slowly drifted to their present positions. This idea was developed by simple observations such as the fact that the African and South-American coast lines fit together like pieces of a puzzle and that fossils and similar sedimentary rocks are found on different continents. Unfortunately his theory didn’t attract much attention until the 50’s. As we indulge in the Theory of Plate Tectonics we start to notice that Plate tectonics unified all of these previous unanswered questions about the oceans and continents. The actual theory of plate tectonics can be defined as “The theory that Earth's outer shell is divided into several plates that glide over the mantle and the rocky inner layer above the core. The plates act like a hard and rigid shell compared …show more content…
The first exponential reason among the classes of evidence for plate tectonics is the shape of many continents and how they look like separated pieces of a jig saw puzzle. Fossil Evidence is another reason supporting plate tectonics. Plants, animals and fossils have been collected around the world that have a direct correlation to one another. An example of this would be the cynognathus which was a land reptile that lived around 240-250 million years ago. Fossils of the cynognathus have been found on both the Africa and South American continents providing evidence that the two continents were once one. Ocean Ridges are another form of evidence that support the tectonic theory. Ocean ridges are a location where plates are constantly separating due to lava bubbling up as the plates pull and push
