The thinner ocean crust sits at lower elevations than the continents, providing the basins which have filled with water, that is, the oceans. At the earliest stages of Earth's history there was little or no continental crust, but a global ocean crust, thinly covered by the primitive ocean....
There are five oceansand seven continents that cover the surface of our planet. In fact,there is only one World Ocean, one big water mass surrounding the seven continents, however, the ocean has been divided into five ocean basins according to geographic location and these basins are commonly ...
The ocean is a huge, mobile reservoir of heat and chemical mass. As such, it is the “engine” that drives weather-climate systems across the ocean basins and the continents, directly affecting food production, drought, and flooding on land. Water is effectively opaque to electromagnetic ...
The ridge divides the sea into two major basins, which are over 3,000 m/ 9,843 ft in depth. On the satellite image to the left, you can see the vertical (from top to bottom) light blue line in the deep blue sea. This is the boundary where the earth's continental places move apa...
The oceans are not uniformly distributed on the face of the earth. Continents and ocean basins tend to be antipodal, or diametrically opposed to one another, i.e., continents are found on the opposite side of the earth from ocean basins. For example, Antarctica is antipodal to the Arctic ...
While the ocean basins lie much lower thansea level, the continents stand high—about 1 km (0.6 mile) above sea level. The physical explanation for this condition is that thecontinental crustis light and thick while theoceanic crustis dense and thin. Both the continental and oceanic crusts li...

The sinking process was made possible by the thickening of the asthenosphere beneath the ocean basins, a process which is continuing towards the continents as these become "oceanized". It is to be expected that the entire process will be completed within the next 30 to 50 MM years....
