世界上最深的海是太平洋馬里亞納海溝。這個(gè)海溝位于西太平洋，從關(guān)島東南方向延伸至馬里亞納群島，是地球上最深的海洋地區(qū)，也是地球上最深的地方之一。這個(gè)海溝的深度達(dá)到了10994米，比珠穆朗瑪峰還要深。這個(gè)海溝的深度是由于沖繩海槽在太平洋板塊與菲律賓板塊相碰撞時(shí)形成的。

The deepest sea in the world is the Mariana Trench in the Pacific Ocean. Located in the western Pacific, extending from Guam to the Mariana Islands, the Mariana Trench is the deepest oceanic area on Earth and one of the deepest places on Earth. The depth of this trench reaches 10994 meters, deeper than Mount Everest. The depth of the Mariana Trench is due to the collision between the Pacific Plate and the Philippine Plate, which formed the Okinawa Trough.
