Today this old seafloor is found along the east coast of Africa from the Somali Basin to the east coast of South Africa and adjacent to Queen Maud Land and Enderby Land in East Antarctica. 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.

The Pacific ocean floor at this site was generated during seafloor spreading from a pattern of ridges and plates that had existed for some unknown period of time. 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. "}}, {"@type": "Question","name": "What is an ocean basin? The evolution contains five stages which areembryonic stage, juvenile stage, mature stage, declining stage, terminal stage, mature stage, and continental collision.

There are three stages in the history of a basin: mature (where a broad ocean basin widens, trenches eventually form, and subduction starts); declining (where the sea floor is eliminated by subduction and an oceanic ridge forms); and terminal (where the sea floor is finally eliminated and continents collide to form a continental mountain chain). ","acceptedAnswer": {"@type": "Answer","text": "The Pacific is the oldest of the existing ocean basins. The Murder Mystery: This is a casino themed murder, Is Tuna A Delicacy? In this stage, the movement that appears and happens is the subsidence of the ocean bottom and it will spread. In the Indian Ocean the oldest segment of seafloor was formed about 165 to 145 million years ago by the rifting away of Africa and South America from Gondwana, a supercontinent consisting largely of the present-day continents of the Southern Hemisphere. Hopefully this article can help you to know more about the formation of the ocean basin. subduction eliminates much of sea floor and oceanic ridge. The Wilson Cycle is a model that describes the opening and closing of ocean basins and the subduction and divergence of tectonic plates during the assembly and disassembly of supercontinents. [4], The Wilson cycle theory is based upon the idea of an ongoing cycle of ocean closure, continental collision, and a formation of new ocean on the former suture zone. Then, to know either the stage of the ocean basin evolution is in the mature stage or not there is a characteristic that you can know. The Tethys seaway also opened during this rifting phase as Europe pulled away from Africa. 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 characteristic is the existence of the continental margins in the sea seafloor that creates the ocean basin.

","acceptedAnswer": {"@type": "Answer","text": "Ocean basin. After the elimination of seafloor and the collide of continents there will be created and or the forming of the continental mountains chain. Ocean basin is virtually the region that contains a huge amount of water. Possibly simultaneously or shortly after this rifting began, South America started to separate from Africa, initiating the formation of seafloor in the South Atlantic Ocean. However, the shape of most past ocean basins needs to be worked out from observations of remnants preserved in continental areas.
