Age Of Ocean Floor Definition

Seabed contains several hundred years worth of cobalt and nickel.

Age of ocean floor definition.

This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. The lack of weathering and erosion in most areas however allows geological processes to be seen more clearly on. Therefore seafloor dating isn t that useful for studying plate motions beyond the cretaceous. The data is from four companion digital models of the age age uncertainty spreading rates and spreading asymmetries of the world s ocean basins.

The ionic growing earth ige posits the same 8 elements that started the earth heated the planet for the first 3 3 5 billion years of its existence see ige fig. This dataset shows the age of the ocean floor along with the labeled tectonic plates and boundaries. Mountains plains channels canyons exposed rocks and sediment covered areas. Exploration of the seafloor and the earth s crust.

Age of the ocean floor a critical analysis. To get the dependence on x one must substitute t x v ax l where l is the distance between the ridge to the continental shelf roughly half the ocean width and a is the ocean basin age. Other articles where ocean floor is discussed. Because of this correlation between age and subduction potential very little ocean floor is older than 125 million years and almost none of it is older than 200 million years.

The following features are shown at example depths to scale though each feature has a considerable range at which it may occur. The arrival of water 1400 mya solidified the molten crust and by 1200 mya submerged. The ocean floor is literally the floor of the ocean. Contours of 20 million years are available as a layer that is currently set to invisible.

Rather than height of the ocean floor above a base or reference level the depth of the ocean is of interest. February 4 2019 eugene ellis. In recent years satellite images show a very clear mapping of the seabed and are used extensively in the study and exploration of the ocean floor. The process that continually adds new material to the ocean floor is seafloor spreading and the continental slope.

For that geologists date and study continental crust.
