[#paragraph3]Although it was eventually supplanted by the theory of plate tectonics, Wegener’s theory of continental drift influenced science because it explained disparate observations, because it was placed in the context of existing theories, and because it offered a coherent view of Earth’s ...
板块的岩石密度低于熔融岩石,因此构造板块,包括承载大陆的板块,漂浮在地幔上。构造板块对大陆漂移的解释的一个重要部分是,地幔中的熔融岩石被迫通过两个板块交汇的大洋中山脊的海底。这种熔融物质为山脊两侧的板块添加了新的海洋地壳。海底从洋中脊向两个方向伸展,脊两侧的构造板块随着新的海洋地壳的增加而相互分离。与...
