Seabed - Wikipedia
WEBThe seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as 'seabeds'. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain.

WEBApr 27, 2022 · What's on the seafloor? The ocean covers more than 70% of the Earth’ surface, yet only a small part of the seafloor has been mapped with enough detail to understand the basic structure, risks, and living and mineral resources that exist there.
Seafloor Spreading - National Geographic Society
WEBNov 29, 2023 · Seafloor spreading is a geologic process in which tectonic plates —large slabs of Earth's lithosphere —split apart from each other. Seafloor spreading and other tectonic activity processes are the result of mantle convection. Mantle convection is the slow, churning motion of Earth’s mantle.
Seafloor spreading | Evidence & Process | Britannica
WEBseafloor spreading, theory that oceanic crust forms along submarine mountain zones, known collectively as the mid-ocean ridge system, and spreads out laterally away from them. This idea played a pivotal role in the development of the theory of plate tectonics , which revolutionized geologic thought during the last quarter of the 20th century.
