   Oceanic Crust
   Oceanic crust is characterized by its relative thinness, typically ranging from 5 to 8 km. Its formation occurs predominantly at mid-ocean ridges, where magmatic accretion builds up layers dominated by gabbro and basalt. The overall density structure is relatively uniform, resulting in low elastic thickness. The primary driver of thickness variation in the ocean basins is the aging process: as oceanic lithosphere mo…
