[4] The first three stages (Embryonic, Young, Mature) describe the widening of the ocean and the last three stages (Declining, Terminal, and Relic Scar/Geosuture) describe the closing of the ocean and creation of mountain ranges like the Himalayas.[3]. Each layer has its own properties, composition, and characteristics. 2 The Red Sea is an embryonic ocean that appears to be starting step by step from the south, where the axial region is underlain by oceanic crust and has a rift valley. 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. flooded by seawater, spreading begins (mid-ocean ridge In the ocean plate, this process causes the seafloor spreading. a) (1) The upper crust is deformed by ductile stretching while the lower crust is broken along normal faults (2) tension pulls apart the crusts and crust slab sink in the middle forming a rift valley (3) continued spreading creates a narrow sea (4) after continued spreading an ocean and ridge system are created.

Below the ocean floor, there are a few small deeper areas called ocean trenches. This kind of movement that allows the formed of rift valley and the splitting of the continent. A defining geomorphic feature of the declining category is that around 1% of their area is trench. Although the oceans are commonly stated as covering 72% of the earth, this figure includes the (submerged) continental shelves, which are geologically extensions of the continents and not part of the ocean basins. In fact, it holds most of the water on earth since ocean basins cover almost three-quarters of the surface on Earth.

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. In . Rigorous plate tectonic analysis, controlled by knowledge of both directions and rates of seafloor spreading, is consequently possible for <5% of earth history.

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. And because of the diverge, the seafloor basalt will be created. And also in this stage you can see that the narrow seas will match the coast perfectly.

Ocean basins form in the beginning by stretching and splitting (rifting) of continental crust, and the increase of mantle fabric and magma into the crack to form new oceanic lithosphere. Our earth surface has different shape in every region. From the case of the Atlantic Ocean, Wilson Cycle plate margins can broadly be described as having the following attributes: A Wilson cycle is not the same as a supercontinent cycle, which is the break-up of one supercontinent and the development of another and takes place on a global scale. As the North Atlantic Ocean continued to develop, seafloor spreading propagated northward.
