The ocean floor, also known as the seabed or seafloor, is the bottom surface of the world's oceans. It is a vast and largely unexplored area that holds significant geological, biological, and ecological importance.
The ocean floor is divided into several major basins, including the Atlantic, Pacific, Indian, Southern, and Arctic Oceans. Each basin has unique characteristics and geological features.
The topography of the ocean floor varies widely. It includes features such as underwater mountains (seamounts), deep-sea trenches, abyssal plains, and mid-ocean ridges. The mid-ocean ridges, for example, are long mountain chains that run through the center of some ocean basins, where tectonic plates are spreading apart.
