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...

This plate tectonic theory was an expanded and detailed version of the previous theory of continental drift originated in the early 20th century. It also touched the seafloor spreading theory originated around 1960’s. Now, below the lithosphere lies the athenosphere. This athenosphere has ...
