I Continental Margin •Atlantic Type (Trailing Edge -Passive) – Subsidence, sedimentation. Starting at … It is bordered by continental margins, which extend seaward in varying degrees of inclination; this inclination determines the amount of water flowing into the basins. The Arctic and Atlantic Ocean basins, for example, are basins that are steadily growing due to the constant tectonic activity in their respective territories. The Pacific Ocean basin, on the other hand, is steadily shrinking. The cycle is known as the Wilson Cycle: (1) Rifting of continents by mantle diapirism (2) Continental drift, seafloor spreading & formation of ocean basins Example of an Oceanic Basin Landform: The oceanic basin picture above is only a small part of the Atlantic Ocean Basin. 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. The ocean basins are partially bounded by the continents, but they are interconnected which is why marine scientists refer to a single “world ocean.” The world ocean is divided into the North and South Pacific, North and South Atlantic, Indian, and Arctic Oceans.

They are part of the same crust (thin, solid outermost layer of Earth) that forms the continents. Erosion is often considered a major factor in contributing to the shrinkage of an ocean basin, along with sedimentation from ocean tributaries and tectonic plate movements. But glacial cycles play out over tens of thousands of years. The depressions lie below sea level. On land, the largest basin is the intermontane basin, a broad area enclosed by higher landforms. Many sources include the continental margins as part of the ocean basins, but the margins are the drowned edges of the continents. sea-floor basalts begin forming as continental sections diverge Red Sea.

Several minor basins, such as those holding the Gulf of Mexico, the Sea of Japan, and the Bering Sea, have been inactive for hundreds, even thousands, of years. The magma then solidifies and the process repeats itself. The Arctic and Atlantic Ocean basins, for example, are basins that are steadily growing due to the constant tectonic activity in their respective territories. A number of major features of the basins depart from this average—for example, the mountainous ocean ridges, deep-sea trenches, and jagged, linear fracture zones. When a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge.
