Oceanic Basin: Definition and Usage
An oceanic basin (or ocean basin) is a large geologic basin that is covered by seawater and lies below sea level. These basins are vast submarine regions that collectively cover nearly three-quarters of Earth’s surface. They contain the overwhelming majority of all water on the planet and have an average depth of almost 4 kilometers (about 2.5 miles).
Oceanic basins are characterized by various features, including oceanic ridges, deep-sea trenches, abyssal plains, and seamounts. They play a crucial role in the Earth’s hydrological and geological processes.
