Is The Ocean Floor Flat

Deep ocean troughs occur in places where one of the earth s plates is being pulled down beneath another and destroyed.

Is the ocean floor flat.

The ocean floor or seabed refers to earth s top most layer of thin basalt rock that is submerged beneath seawater. Tides and ocean currents. Other articles where ocean floor is discussed. The process that continually adds new material to the ocean floor is seafloor spreading and the continental slope.

Sediments comes from various sources. The ocean floor has the same general character as the land areas of the world. These ridges mark the sites where the earth s surface plates are being created. Plate tectonics and the ocean floor.

On average oceanic crust is only 6 to 7km thick compared to 35 to 40km for con tinental crust. The smooth flat regions that make up 40 of the ocean floor are the abyssal plain. Mountains plains channels canyons exposed rocks and sediment covered areas. The ocean basins are characterized not only by lying in deep water the ocean floor averages about 4km below sea level but also by being underlain by a thin layer of crust.

The lack of weathering and erosion in most areas however allows geological processes to be seen more clearly on. The globe isn t flat and neither are the world s oceans. Seabed topography is flat where sedimentation is heavy and covers the tectonic features. The floor of the ocean has a very varied topography.

The difference is sea level is caused by two major factors. Land erosion sediments brought mainly by rivers. A series of volcanic ridges cuts through all the oceans. We have big news.

Exploration of the seafloor and the earth s crust. Bathymetry the shape of the ocean floor is largely a result of a process called plate tectonics the outer rocky layer of the earth includes about a dozen large sections called tectonic plates that are arranged like a spherical jig saw puzzle floating on top of the earth s hot flowing mantle. We re aren t just talking about the ocean floor but the actual surface of the ocean. Like even the flattest grasslands the world s oceans have varied elevations.

Is the ocean floor flat. Regions of the ocean floor can be distinguished by topographical margins e g.
