The theory of plate tectonics describes the motions for the lithosphere, the comparatively rigid outer layer of the Earth that includes all the crust and part of the underlying mantle. The lithosphere is divided into a few dozen plates of various sizes and shapes, in general the plates are in...

The Theory of Plate Tectonics The idea that continents moved during the past goes back to the time when people first noticed that the margins of eastern South America and western Africa looked as if they fit together. Geologists also noticed that similar or identical fossils occur on widely ...

in the early days of the development of the theory of plate tectonics.Canadian geophysicist Tuzo Wilson realized that this age progression could result if the islands were formed on a surface plate moving over a fixed volcanic source in the interior.Wilson suggested that the long chain of volcano...
Mantle convection is the most widely studied method of tectonic plate movement and it is very similar to the theory developed by Holmes in 1929. There are large convection currents of molten material in the Earth's upper mantle. As these currents transmit energy to the Earth's asthenosphere (...
Plate Tectonic Theory:Plate tectonic theory describes the dynamic nature of the tectonic plates that together make up the Earth's lithosphere. There are around seven major tectonic plates and several minor plates that comprise the mosaic nature of the Earth's crust. The theory of plate tectonics ...
The Plate tectonic theory says the seafloor is spreading all along the Mid-Oceanic Ridge. So at that intersection point, spreading should be occurring in four directions—on both sides of two ridge axes. A deep hole should be opening up at that point. It is no! As will be explained ...
