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. Among the major ocean basins, the Atlantic has the simplest pattern of ocean-floor ages.
What causes ocean basins?
Over millions of years, ocean basins open and close, continents move and change shape, and mountains are pushed up and eroded away. Such dynamic processes continually reshape the surface of the Earth. The movement of rigid plates on the Earth’s surface, known as plate tectonics, is the cause of these changes.

What is the importance of ocean basins?
Extensive mixing takes place across ocean basins, reducing differences between them and making the Earth’s ocean a global system. On their journey, the water masses transport heat, gas and matter around the globe. This circulation has a large impact on the climate of our planet.
