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。
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。
