It is difficult to see how the theory applies to the plate between the Mid-Atlantic Ridge and the ridge in the Indian Ocean.
很难看出这个理论如何适用于大西洋中脊和印度洋脊之间的板块。
As the new crust cools, it sinks under its own weight-a process called subsidence-so the seafloor should be deeper the farther it is from a mid-ocean ridge.
随着这种新地壳的冷却，它会在自身重力的作用下凹陷下去，这个过程被称为“沉降”。因此，在距离海洋中部山脊越远的地方，海底就应该越深。
The result: underwater mountains and hills all along the axis of the mid-ocean ridge.
其结果便是：沿着大洋中脊形成了海底山脉和山丘。
As magma rises under the mid-ocean ridge, ferromagnetic minerals in the magma become magnetized in the direction of the magma become magnetized in the direction of the geomagnetic field.
当岩浆从中海脊下涌起的时候，岩浆中的磁铁矿物质按地磁场的方向被磁化。
This area is considered a "normal" mid-ocean ridge, meaning it exhibits many volcanic features, like seamounts, scientists would expect to find at places like the GSC.
这一区域被认为是“标准的”(normal)大洋中脊，也就是说它具有包括海山在内的多种火山地貌，正是科学家们在加拉帕戈斯扩张中心的理想观测点。
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。
Both island arc and mid-ocean ridge magmas apparently come from the mantle yet they have different compositions.
岛弧和洋中脊火山岩都明显来自地幔然而他们有不懂的组成。

The study of geochemistry indicates that these metabasic volcanic rocks are characterized with N-type MORB (mid-ocean ridge basalt).
地球化学研究表明，其为典型的大洋拉斑玄武岩（MORB型玄武岩）。
Iceland is peculiarly volcanic because it is formed by the intersection of a hotspot and a mid-ocean ridge.
冰岛尤其是由火山构成的，因为它是由一个热点和一个海中间的脊的交点形成的。
Iceland is a European island country in the North Atlantic Ocean on the Mid-Atlantic Ridge.
冰岛是北大西洋上的大西洋中脊一个欧洲岛国。
As magma rises under the mid-ocean ridge, ferromagnetic minerals in the magma become magnetized in the direction of the geomagnetic field.
当岩浆从中海脊下涌起的时候，岩浆中的磁铁矿物质按地磁场的方向被磁化。
