Written and fact-checked by The Editors of Encyclopaedia Britannica Last Updated: Dec 9, 2024 German meteorologist Alfred Wegener is often credited as the first to develop a theory of plate tectonics, in the form of continental drift. Bringing together a large mass of geologic and paleontological...
Chapter 2: Plate Tectonics Theory of plate tectonics “Plate Tectonics” explains why the plates of the earth are moving. The main idea (theory) was proposed by Alfred Wegener in 1912. Earth’s crust consists of plates that move or float on the mantle Movement is caused by convection current...
The theory of plate tectonics was developed from the 1950s to the 1970s. It is the modern update tocontinental drift, an idea first proposed by scientist Alfred Wegener in 1912, who that Earth’s continents had "drifted" across the planet over time. Wegener didn't have an explanation for ...
when the theory ofplate tectonicswas proposed. According to this theory, the continents move apart by riding piggyback on plates—huge slabs of the Earth's lithosphere—that are much larger than the continents themselves. The plates move like parts of a conveyor belt powered by huge convection ...

Developed from the 1950s through the 1970s, plate tectonics is the modern version of continental drift, a theory first proposed by scientist Alfred Wegener in 1912. Wegener didn’t have an explanation for how continents could move around the planet, but researchers do now. Plate tectonics is ...

The initiation mechanism of Earth’s plate tectonic cooling system remains uncertain. A growing consensus suggests that multi-plate tectonics was preceded by cooling through a single-plate lithosphere, but models for how this lithosphere was first broken
