The coastal shelf that stretches to depths of about 600 feet, is narrow along North and South America, but is comparatively wide along Asia and Australia. Despite the fact that there is only one ocean in the world, it has historically been split into the Arctic, Atlantic, Indian, and Pacific ocean basins.

Geological Society, London, Special Publications. These boundaries are common areas of tectonic activity, which is the deformation of the earth's crust due to movement of tectonic plates resulting in activity (such as earthquakes, volcanoes and mountain building).

It is divided into 6 stages namely: 1. 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 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. Stages of Ocean Basin ACTIVE Evolution -regions below sea level. Written By: Ocean basin, any of several vast submarine regions that collectively cover nearly three-quarters of Earths surface. . In the ocean plate, this process causes the seafloor spreading. The Four LayersThe crust is made of the lightest materials (rock- basalts and granites) and the core is made of heavy metals (nickel and iron).Many geologists believe that as the Earth cooled, the heavier, denser materials sank to the center and the lighter materials rose to the top. A case study of the Wilson Cycle can be seen with the development of the Atlantic Ocean. During this period spreading continued in the Pacific basin with the growth of the Pacific Plate and the consumption by subduction of its bordering plates, including the Izanagi, Farallon, and Phoenix. ocean basin widens, trenches develop and subduction begins, subduction "}}, {"@type": "Question","name": "Which ocean basin is the youngest?

The evolution contains five stages which are embryonic stage, juvenile stage, mature stage, declining stage, terminal stage, mature stage, and continental collision.

The key features of the oldest latest ocean basin were shaped by the phenomena linked with plate tectonics. The Wilson cycle begins with a rising plume of magma and the thinning of the overlying crust. This resulted in the cessation of a long history of subduction in the area and the gradual conversion of this continental margin to a transform fault zone.
