Deep Ocean Trenches: The Subduction Zones In contrast to mid--ocean ridges, deep ocean trenches form at convergent plate boundaries, where one plate descends, or 'subducts, ' beneath another.

深海海沟：俯冲带 与洋中脊相反，深海海沟形成于会聚板块边界处，其中一个板块下降或“俯冲”到另一个板块下方。

As this oceanic plate subducts or gets moved underneath this continental plate, things like water and carbon dioxide and other materials get squeezed out of it, like ringing a wet washcloth.

当这个海洋板块俯冲或移动到这个大陆板块下方时，水、二氧化碳和其他物质会被挤出， 就像弄湿毛巾一样。
