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。
Airplanes occasionally crash into water but rarely in mid-ocean, where the uncharted bottom is dark and can be treacherous even for unmanned diving equipment.
飞机偶尔会坠入水中，但很少会坠毁在大洋中部，这里的海底状况未知，光线黑暗，即便对无人驾驶潜水设备来说也变幻莫测。
