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。
Its existence depends entirely on what geologists call the mid-Atlantic ridge.

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。
Iceland lies on the Mid-Atlantic Ridge, the volatile meeting of the Eurasian and North American continental plates.
冰岛位于大西洋中部的脊上，是亚欧大陆和北美板块的交界活动处。
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）。
The divergent Mid-Atlantic Ridge rises above sea level at Thingvellir, with the North American plate to the west and the Eurasian plate to the east.
分歧中大西洋海中脊升起海拔在辛格韦德利，和北美板块在西部和欧亚板块在东部。
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。
A geologically young land, Iceland is located on both the Iceland hotspot and the Mid-Atlantic Ridge, which runs right through it.
一块地质学年轻的土地，冰岛位于冰岛热点和大西洋中部脊，这一直透过它运转。
About 100 million years from now the present-day Mid-Atlantic Ridge will be subducted and the continents will come closer together.
大约在距今一亿年之后，大西洋的中洋脊将会隐没，大陆和大陆之间则会越靠越近了。
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。
The Mid-Atlantic Ridge is an example of a divergent plate boundary and is an area where new seafloor is being created.
