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. An example for the mature stage is the Atlantic Ocean. As was noted earlier, the oldest known oceanic crust (estimated to be about 200 million years old) is located in the far western equatorial Pacific, east of the Mariana Island arc. the lower crust is broken along normal faults; (2) tension pulls 1 ), a quantitative assessment of geomorphic features that characterise ocean basins at different stages of their evolution has not previously been completed. continued spreading, an ocean and ridge system are created. sea-floor basalts begin forming as continental sections diverge.

The crust, the mantle, the outer core, and the inner core, in that order, are the layers that make up our planet and affect many of its major processes. And because of the diverge, the seafloor basalt will be created. ocean basin widens, trenches develop and subduction begins, subduction India began drifting northward directly toward Asia. d) (1) The upper crust is broken along normal faults while the It has been suggested that Wilson cycles on Earth started about 3 Ga in the Archean Eon. In the ocean plate, this process causes the seafloor spreading. Another example of the terminal stage is the Persian Gulf. narrow, closing seas, Persian Gulf small remnant of ancient Tethys Sea, almost completely What are the four stages a continental plate goes through to become an ocean? However, the shape of most past ocean basins needs to be worked out from observations of remnants preserved in continental areas. 1. In this stage the rift valley is formed while the continent is begins to split. The characteristic is the existence of the continental margins in the ocean seafloor that creates the ocean basin.

The movement that appears in this stage is the uplift of the bottom part of the ocean. Stages of Ocean Basin ACTIVE Evolution -regions below sea level. During this same period, Europe, joined to Greenland, began drifting away from North America, which resulted in the emergence of the seafloor in the Labrador Sea and the northernmost Atlantic Ocean. It either was created by spreading in the Pacific basin and subsequent capture by the formation of the Bonin and Mariana arcs, or it resulted from backarc spreading behind trenches to the south. Together they comprise the overpowering majority of all water on this planet and feature a typical depth of virtually 4 km (about 2.5 miles).
