If you could push Africa and south America together, they would meet at the Mid - Atlantic Ridge and close up the ocean between them. 如果你能把非洲和南美洲放在一起，他们一定会在中大西洋海岭处吻合，并封死它们之间的海域。
Denmark is trying to prove that a detached part of the underwater Lomonosov ridge is an extension of Greenland, which is Danish territory. 丹麦正在试图证明，从水下的罗蒙诺索夫海脊分出的一部分，是丹麦领土格陵兰岛的延伸。
Hence peridotite modes can be used to reflect efficiently mantle melting and melt extraction processes beneath ocean ridges only if the excess olivine is removed appropriately. 为此，只要把深海橄榄岩中过量的橄榄石剔除后，其实际矿物组分就能有效地反映洋脊下地幔熔融作用和熔融萃取过程。
