what are ocean basins quizlet?
610641
The shallow sea floor that is located between the shoreline and the deep-ocean bottom. Deep-ocean basin. The part of the ocean floor that is under deep water beyond the continent margin and that is composed of oceanic crust and a thin layer of sediment. Continental shelf.

Main Points The ocean has three main layers: the surface ocean, which is generally warm, and the deep ocean, which is colder and more dense than the surface ocean, and the seafloor sediments. The thermocline separates the surface from the deep ocean.

The ocean has an interconnected current, or circulation, system powered by wind, tides, the Earth's rotation (Coriolis effect), the sun (solar energy), and water density differences. The topography and shape of ocean basins and nearby landmasses also influence ocean currents.

A continental shelf is part of the ocean, but also part of the continent. To geographers, continents are also culturally distinct. The continents of Europe and Asia, for example, are actually part of a single, enormous piece of land called Eurasia.

The ocean gyres in the major ocean basins form large, roughly circular, closed currents which are centered at a latitude of approximately (0) (30) (60) degrees. 5. As seen from space, the gyre circulation patterns in the Northern Hemisphere show a (clockwise) (counterclockwise) flow.

Name the major divisions of the global ocean. The global ocean is divided into five major oceans are Atlantic, Pacific, Indian, Arctic and Southern Oceans. A body of salt water that covers nearly three-fourths of Earth's surface.

Tectonic plates, the massive slabs of Earth's lithosphere that help define our continents and ocean, are constantly on the move. Plate tectonics is driven by a variety of forces: dynamic movement in the mantle, dense oceanic crust interacting with the ductile asthenosphere, even the rotation of the planet.

Properties of Ocean Water Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity.

definition. Oceanic islands are those that rise to the surface from the floors of the ocean basins. Continental islands are simply unsubmerged parts of the continental shelf that are entirely surrounded by water. Many of the larger islands of the world are of the continental type.…

The Pacific, Atlantic, and Indian are the most commonly known. The Southern Ocean is the 'newest' named ocean basin.

The seabed (also known as the seafloor, sea floor, or ocean floor) is the bottom of the ocean, no matter how deep. All floors of the ocean are known as 'seabeds'.

Ocean and gulf are large water bodies. Gulf is only part of the Ocean.

An ocean is a vast and continuous frame of salty water that shelters almost 70 percent of the total earth's surface while a sea is a large body of saline water that occupies a greater part of the world's surface but is smaller than an ocean.

Principal characteristics. Oceanic ridges are found in every ocean basin and appear to girdle Earth. The ridges rise from depths near 5 km (3 miles) to an essentially uniform depth of about 2.6 km (1.6 miles) and are roughly symmetrical in cross section. They can be thousands of kilometres wide.

The Mid-Atlantic Ridge is a divergent plate boundary. These boundaries are interesting places on the surface of the Earth.

Ocean gyres are large system of circular ocean currents formed by global wind patterns and forces created by Earth's rotation. The five major circulation patterns formed by the currents on this map are the world's five major ocean gyres: North Atlantic, South Atlantic, Indian, North Pacific, and South Pacific.
