英汉例句

• This is part of the system of mid-ocean ridges that form as the tectonic plates of the Earth「s crust move apart-a process known as sea floor spreading.

  印度洋脊是中大洋脊的一部分，中大洋脊是地壳分离的地球板块形成的。这一形成过程被称为海底扩张。

• Much of the activity between the continental shelves takes place deep underwater at the mid-ocean ridges.

  大部分的大陆架的活动发生在深水下的大洋洋底的海脊。

• 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「标準的」(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。

• Both island arc and mid-ocean ridge magmas apparently come from the mantle yet they have different compositions.

  岛弧和洋中脊火山巖都明显来自地幔然而他们有不懂的组成。

• As magma rises under the mid-ocean ridge, ferromagnetic minerals in the magma become magnetized in the direction of the geomagnetic field.

  当巖浆从中海脊下涌起的时候，巖浆中的磁铁矿物质按地磁场的方向被磁化。

• For example, as the atmospheric carbon-dioxide level in Hawaii goes up, the ph at a mid-ocean mooring about 450km to the north-west goes down (see chart).

  例如在夏威夷，大气中二氧化碳浓度在升高，其西北方向约450公里处海洋监测点的PH值在下降(见图表)。

• 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。

• 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。

• As the rocks cool from lava, for instance at the deep mid-ocean ridges where the earth」s surface plates are formed, crystals line up with the direction of the magnetic field.

  举例来说由熔巖冷却的而来的巖石，位于深深的海中央山脊的地方就形成了地球表面的板块，水晶晶体排列方向与磁场方向一致。

• 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.

  当巖浆从中海脊下涌起的时候，巖浆中的磁铁矿物质按地磁场的方向被磁化。
