A Dictionary of Earth Sciences. More specifically, it is a saucer-shaped depression under sea level, allowing the seawater to flow into it.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.

Magma rising in a conduit beneath the seafloor may meet a layer of unconsolidated wet sediment and in most cases, the magma will be more dense than the wet sediment. However, the date of retrieval is often important. Magma rising in a conduit beneath the seafloor may meet a layer of unconsolidated wet sediment and in most cases, the magma will be more dense than the wet sediment. Because oceans lie lower than continents, the former serve as sedimentary basins that collect sediment eroded from the continents, known as clastic sediments, as well as precipitation sediments. The waters along the continental shelf are usually productive, both … Lying generally between the foot of a continental rise and a mid-ocean ridge , abyssal plains cover more than 50% of the Earth 's surface. To quantify spatial and temporal scales of temperature and salinity variations, we estimate the autocorrelation function and associated decorrelation scales for the Amerasian Basin of the Arctic Ocean.
