由于现代珊瑚礁的堆积速率大于地壳沉降速率，可能会形成更多的灰沙洲或灰沙岛。
However its present accumulation rate surpasses its subsidence rate, resulting in the accumulation of more lime-sand islets.
研究表明，洞庭湖仍处于不断沉降中，在平水位以下或洪水位以上，地壳沉降速率均大于泥沙淤积速率。
The research shows that Dongting Lake is still subsiding at the level both below water and above flood, and the velocity of the crust Subsidence all exceeds that of bedload's filling up.
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。
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.
