These patterns showed that new crust was being formed at mid--ocean ridges and slowly moving away on either side, a process known as sea--floor spreading.

这些模式表明，新的地壳正在大洋中脊处形成，并缓慢地向两侧移动，这一过程称为海底扩张。

Life at the Rifts and Trenches While the conditions at mid--ocean ridges and deep--sea trenches are extreme, with high pressures, temperatures, and total darkness, life has found a way to thrive.

裂谷和海沟中的生命虽然洋中脊和深海海沟的条件极其恶劣，高压、高温和完全黑暗，但生命却找到了繁衍生息的方法。

1000 years from now, since the ocean floor is spreading at a fast rate, 5 centimeters a year in the mid-Atlantic ridge, in a millennia, it will have spread a whopping 46 meters or 154 feet.

距今 1000 年之后，由于洋底正以每年 5 公分的速度在大西洋中部海脊快速扩张，到一千年后，它将扩展到惊人的 46 公尺或 154 英尺。
