Mid-Ocean Features
Many features of the ocean floor are located in the ocean basin. The ocean basin is the area far from the continental margin. In the ocean basin, deep canyons called trenches cut into the ocean floor. Underwater mountain chains called mid-ocean ridges run more than 56000 km through the world ocean. Most mountains in the mid-ocean ridges reach more than 1500 m high. Some peaks stick out of the water as islands.
