What materials make up the four layers of the earth? In addition, usually the geologist will see either there is a island arcs and the island trenches around the basin edge or not. And because of the diverge, the seafloor basalt will be created. 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.

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. Continued closure between Africa and Europe, which began about 100 million years ago, caused the isolation of the Mediterranean Sea, so that by 6 million years ago this water body had completely evaporated. The seafloor in the western portion of the Philippine Sea developed between 60 and 35 million years ago. 1. Part of Springer Nature.

With an average depth of 3,700 meters, experts have also divided the world ocean into various zones based on depth from the surface for ease of oceanographic studies. The characteristic is the existence of the continental margins in the ocean seafloor that creates the ocean basin. There are some stages of ocean basin evolution. Ocean basins form initially by the stretching and splitting (rifting) of continental crust and by the rise of mantle material and magma into the crack to form new oceanic lithosphere. last of the sea floor is eliminated and continents collide, The Red Sea Forming a new ocean basinLife Cycle of an OceanTypes of Faults, Extensional pulling apart, normal fault, Compressional pushing together, thrust fault, The type of faults show the direction of stress, rift valley deepens and is flooded by seawater, Red Sea(true ocean basin, but still narrow), Gulf of Aden(becoming an open ocean basin), ocean basin with spreading center & continental margins, trenches / volcanic island arcs / coastal mountain ranges, convergence continental blocks squeeze ocean basin, collision / regional uplift / narrow, closing seas, Persian Gulf small remnant of ancient Tethys Sea, almost completely closed, continental collision with regional uplift, extension of the MOR spreading center in the Indian Ocean.
