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 ...

Theory of Continental Drift Proposed by Alfred Wegener in 1912. Basic belief that all of the continents were once joined together in a ‘supercontinent’. Met much resistance because Wegener did not have a good model to explain how the continents moved apart. Although the theory was discarded, ...
The meaning of PLATE TECTONICS is a theory in geology: the lithosphere of the earth is divided into a small number of plates which float on and travel independently over the mantle and much of the earth's seismic activity occurs at the boundaries of thes

简介魏格纳起初从大西洋两岸的弯曲形态受到启发,于1912年提出了大陆漂移的简介,1915年著成《海路的起源》一书,全面系统地论述了大陆漂移问题。大陆漂移说立足于陆块漂移得地壳均衡论。他认为,地球上所有大陆在中生代以前是统一的联合古陆,或...
