events are major pieces of evidence towards proving that the platetectonicstheory is valid.
The theory of tectonicplateswas first posed by Alfred Wenger in 1912. Is the theory of how the earth lithosphere is made up of many separate pieces of the earth’s crust known as tectonicplates. He put forward...
Volcanic and Seismic events are major pieces of evidence towards proving that platetectonicstheory is valid.
A seismic event is the transient motion and release of kinetic energy caused by sudden failure of the earth's crust, usually felt as shaking or tremors in the rock mass. Seismic events range...
This paper will probe the theory that the continents of the Earth were originally a single supercontinent. It will describe the reasoning behind the theory, review the evidence that supposedly supports it, and present the reasoning for its rejection. It will also present an alternative view. It will...
Platetectonics is a scientific theory that describes the large-scale motions of Earth's lithosphere. The model builds on the concepts of continental drift, developed during the first few decades of the 20th century. The geoscientific community accepted the theory after the concepts of seafloor spreading...

The History of platetectonics
Before the platetectonics revolution of the 1960’s geographers had a very basic understanding of global geological phenomena’s. while there had been many theory’s put fort that were used to try and explain these phenomena’s none had been completely successful till finally...
Alfred Wegner as part of his wider theory on platetectonics. The platetectonictheory suggested by Alfred Wegner in 1915 was that millions of years ago all the continents were joined together in one mass of land called ‘Pangaea’, the evidence for this was that coal was found on Antarctica, the shape...

In geologic terms, a plate is a large, rigid slab of solid rock. The word tectonics comes from the Greek root "to build." Putting these two words together, we get the term platetectonics, which refers to how the Earth's surface is built of plates. The theory of platetectonics states that the Earth's...
Tectonics and Continental Drift Past and Present Locations
When we look at our earth’s surface now it has seven continents, and five of them are divided by the oceans that surround them. In 1912 Alfred Wegner (1880-1930), came up with a theory called the continental drift;...

Introduction: Tracking Past Plate
The evidence in support of plate motions comes
from measurements made with the Global
Positioning System (GPS).
However, evidence of past plate motions is not
obtained through GPS.
