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...
Passage Three The theory of plate tectonics describes the motions of 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 ...
According to this theory, Earth’s surface consists of a number of rocky tectonic plates. The plates fit together at their edges but are not attached to each other. The part of plates that make up the seafloor is called oceanic crust. The continents are just the parts of tectonic plates ...
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 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 ...

Plate Tectonics Plate tectonics theory explains the global distribution of mountains, earthquakes, volcanoes, ocean basins and rift valleys on the surface of the Earth. What is the theory of plate tectonics? Plate tectonics theory explains that several plates move on top of the soft mantle. Scienti...
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 (...
