海沟 Oceanic trench

(重定向自Ocean Trench)

海沟是位于海洋中的两壁较陡、狭长的、水深大于5000米(如毛里求斯海沟5,564米)的沟槽。

海沟多分布于活动的海洋板块边缘,在海洋板块与大陆板块的交界处,一般认为它是地球板块相互挤压作用的结果。

世界大洋约有30条海沟,其中主要的有17条,属于太平洋的就有14条,环太平洋的地震带也都位于海沟附近。地球上最深也最知名的海沟是马里亚纳海沟,它位于西太平洋马里亚纳群岛东南侧,深度大约11,034米。

The oceanic trenches are hemispheric-scale long but narrow topographic depressions of the sea floor. They are also the deepest parts of the ocean floor. Oceanic trenches are a distinctive morphological feature of convergent plate boundaries, along which lithospheric plates move towards each other at rates that vary from a few mm to over ten cm per year. A trench marks the position at which the flexed, subducting slab begins to descend beneath another lithospheric slab. Trenches are generally parallel to a volcanic island arc, and about 200 km (120 mi) from a volcanic arc. Oceanic trenches typically extend 3 to 4 km (1.9 to 2.5 mi) below the level of the surrounding oceanic floor. The greatest ocean depth to be sounded is in the Challenger Deep of the Mariana Trench, at a depth of 11,034 m (36,201 ft) below sea level. Oceanic lithosphere moves into trenches at a global rate of about 3 km/yr.
