A submarine plateau is an underwater landform that rises sharply from the ocean floor but is still submerged beneath the water. These plateaus are typically found at depths of 200 to 1,500 meters and can extend for hundreds of kilometers. They are often formed by volcanic activity or the accumulation of sediments over time. Submarine plateaus can be rich in marine life and are important for biodiversity. They provide habitats for various species and can also be significant for human activities, such as fishing and oil exploration. Examples of notable submarine plateaus include the Challenger Plateau and the Seychelles Plateau.
