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 ...
crusts than Earth, which may render subduction and hence plate tectonics less efficient98,99. Therefore, in the absence of any other estimates of the likelihood of sustaining density-driven tectonics on exoplanets, the value proposed by Unterborn et al.98will have to serve for our estimation of...

A new plate tectonics structural model is proposed for the development of the Western Canada Sedimentary Basin (WCSB). This model is based upon the recognition of complex regional rhomboidal fault patterns using Thematic Mapper imagery. ... M. Posavec - 《Williston Basin Symposium》 被引量: 0发...
increased their understanding of the ocean floor via mapping, discovered its mid-ocean ridges, and learned more about its age. In 1961 and 1962, scientists proposed the process of seafloor spreading caused by mantle convection to explain the movement of the Earth's continents and plate tectonics....
