The crustal accretion along mid-ocean ridges is known to be spreading-rate dependent. Along fast-spreading ridges, two-dimensional sheet-like mantle upwelling creates relatively uniform crust. In contrast, the crust formed along slow-spreading ridges shows large along-axis thickness variations with thi...
Underwater photography is also important in mapping parts of theocean floor. 水下摄影在绘制部分海床图时也是很重要的一个方法. 期刊摘选 Recentocean floordata confirm the first part of this slow process. 近来洋底资料证实了这一缓慢过程的第一部分. ...
If that happens, slab pull could draw the oceanic crust under the continent, actually causing the Americas to move eastward toward Europe and the ocean floor to get smaller. That is, the Atlantic Ocean would start to close up, narrowing the distance between the eastern edge of the Americas ...
Ocean tideshave the same frequencies as solid Earth tides, but they derive from both the vertical and (small) horizontal components of the TGP that generates water movement in shallow areas such as thecontinental shelves. This variable water depth loads the crust and modifies the amplitudes of th...
