Ocean Floor Cross Section

If the depth of the ocean is measured along a line drawn straight out from a continental shore the following sequence of bottom features are typically seen.
Ocean floor cross section. Diagrammatic cross section of an ocean basin showing the various geographic features 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. A cross section of the sea floor recreated in a coffee table. Plate tectonics and the ocean floor. At the arrow labeled i the rift valley the igneous rock of the sea floor is so young that it can be accurately dated using carbon 14 dating.
The figure below represents a cross section of the sea floor through a mid ocean rift valley with alternating patches of black and white indicating sea floor with reversed magnetic polarities. Benthos is the community of organisms which live on in or near the seabed the area known as the benthic zone. It is composed of several layers not including the overlying sediment. Glue these two pages together to form the cross section through the earth.
3 turn the shoe box over so that the opening is down. Glue the cross section sheets that you have just glued together to the long side of the shoe box. Oceanic crust is about 6 km 4 miles thick. Cross section of the north atlantic ocean basin from the u s.
The diagram above is a drawing of the bottom profile of the north atlantic ocean basin from the u s. The surface of the abyss horizon table looks like a bathymetric map of the ocean floor rendered in 3 d. The surface of the ocean should be even with the top of the shoe box while the volcano wiill stick up a bit. Oceanic crust the outermost layer of earth s lithosphere that is found under the oceans and formed at spreading centres on oceanic ridges which occur at divergent plate boundaries.
Coast to europe showing the major features of the ocean floor. 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.
