And because of this factor, we can see that there are a lot of difference on the seafloor in one certain ocean compare to another oceans. Written By: Ocean basin, any of several vast submarine regions that collectively cover nearly three-quarters of Earths surface. Ocean basins are formed by the stretching and splitting (rifting) of continental crust, followed by the rise of mantle material and magma into the crack to form new oceanic lithosphere.

The Murder Mystery: This is a casino themed murder, Is Tuna A Delicacy? Seismic tools currently exist to better test the proposed transmogrification of ocean basins into continent, and this hypothesis highlights our continued need to explore the deep seismic structure of continental crust. The majority of the ocean basins on Earth were created by either subduction or seafloor spreading, two types of plate tectonic activity.

The Wilson Cycle can be described in six phases of tectonic plate motion: the separation of a continent (continental rift), formation of a young ocean at the seafloor, formation of ocean basins during continental drift, initiation of subduction, closure of ocean basins due to oceanic lithospheric subduction, and finally, collision of two continents and closure of the ocean basins. Basically, each stage has some characteristic that can be seen to know in which stage the ocean basin evolution is. A classic example of the Wilson Cycle is the opening and closing of the Atlantic Ocean. Along the west coast of North America, the Pacific Plate and the North American Plate converged along what is now California shortly after 30 million years ago. Australia began drifting northward, away from East Antarctica, creating seafloor there. In fact, it holds most of the water on the earth since ocean basins cover almost three-quarters of the surface on Earth. Declining, Mature and Embryonic are all stages of Ocean basin evolution.

Agents of metamorphism include temperature, pressure, and fluids. South Atlantic Ocean seafloor spreading began along the Congo-Sao Francisco Craton around 112 Ma. Meanwhile, Juvenile stage makes the existence of oceanic crust occur below the sea level with the shape of thin and dense. It has been suggested that Wilson cycles on Earth started about 3 Ga in the Archean Eon. An example for the mature stage is the Atlantic Ocean.
