| In the basin on the eastern side of the MAR the Walvis Ridge blocks the northward passage. |
| The exploration of the MAR in the 1950s led to the general acceptance of seafloor spreading and plate tectonics. |
| The MAR divides the Atlantic longitudinally into two halves, in each of which a series of basins are delimited by secondary, transverse ridges. |
| Most of the MAR runs under water but where it reaches the surfaces it has produced volcanic islands. |
| The exploration of the MAR in the 1950s lead to the general acceptance of seafloor spreading and plate tectonics. |
| The MAR is a barrier for bottom water, but at these two transform faults deep water currents can pass from one side to the other. |
