Geologically, there are other undersea geomorphological features such as the continental shelves, the deep ocean trenches, and the undersea mountain ranges (for example, the Mid-Atlantic Ridge and the Emperor Seamounts) which are not considered to be part of the ocean basins; while hydrologically, oceanic basins include the flanking cont…  Moka Stephanie Ijeoma - 5A* three parallel ridges and four basins (also known as deeps). . K. Lee The Southern Ocean is now the fourth largest of the These elevated ridges mark the area where sections of oceanic crust are pulling apart from each other. In hydrology, an oceanic basin may be anywhere on Earth that is covered by seawater, but geologically, ocean basins are large geologic basins that are below sea level. Greenland and Europe, is considered the fifth ocean subdivision. Although not For the other 100 Level topics in Mathematics, they will soon be available. It is characterized by variable rate of ocean floor spreading which reach 15cm/year nearby Easter Island. This creates gaps where hot molten rock, called magma, from the earth's mantle can rise up. For the Deep Sea Plain, the height of the water column is divided into three zones namely: (1) Sunlight Zone (0 – 200m) (2) Twilight Zone (200 – 1000m) (3) Midnight/Darkness Zone (Beyond 1000m). See the diagrams for illustration. The depth of the shelf also varies, but it is generally limited to water shallower than 150 m (490 ft). Ocean Basin is divided into five basically, namely: (1) Continental shelf (2) Continental Slope (3) Deep Sea Plain (4) Ocean Ridge (5) Ocean Deep/Trench. THE OCEAN BASIN The world ocean basin is an extensive suite of connected depressions (or basins) that are filled with salty water; covering 72% of the Earth’s surface. kilometers (5.4 million square miles). The depressions lie below sea level. and almost all of the Scotia Sea. The ocean basins contain many extraordinary geological features, including deep trenches and vast mountain ranges.

Mariana Trench is the deepest part of the world’s oceans. B - Ocean basins are composed of the seafloor and all of its geological features (such as islands, trenches, mid-ocean ridges and rift valleys) and vary in size , shape and features due to the movement of Earth’s crust (lithosphere). For example, the largest mountain range on A new Physics textbook titled “Calculations in Physics for College Students” for Science students is out. Ajayi Ifeoluwa Jeremiah - 3A1,  2B2,  2B3 The break in the ridge at the equator, called the Romanche furrow, is the Canada and Makarov basins, and the mid-ocean ridge on the Eurasian Ocean by the Drake Passage along 68° West longitude. Thus the only existing oceanic lithosphere is younger than about Jurassic in age and occurs at locations farthest from the oceanic spreading centers. This results into an area of relatively shallow water known as a shelf sea. plate tectonics Because of plate tectonics, however, most oceanic lithosphere eventually is subducted.

A bathymetric profile (cross-section) of a major ocean basin like the Pacific Ocean shows the typical features of the seafloor: continental shelf, continental slopeand rise, mid-oceanic ridge, ocean trench, and abyssal plain. The only exception are the crests of the spreading centres where new ocean floor has not existed long enough to accumulate a sediment cover. This is located in Mariana Trench, at a depth of 11,034 m (36,201 ft) below sea level. The deepest point in the Arctic Ocean is 5,450 meters (17,880 feet).
