Mid ocean ridges are divergent boundaries where convection currents in the mantle lift the ocean floor and produce a rift in the lithosphere that follows the crest of the ridge.

The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.

Published today this is the most detailed map of the ocean floor ever produced using satellite imagery to show ridges and trenches of the earth s underwater surface even for areas which have.
Major ports and cities.
New lithosphere is created by volcanic activity along the crest of the ridge and the plates on either side of the ridge are moving away from one another.

This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.
This is expensive and time consuming so sonar maps are mostly only made of places where ships spend the most time.

Researchers have built a detailed map of the ocean floor s topography by using satellites to spot subtle watery lumps on the ocean s surface.
This involved little guesswork because the idea of sonar is straight forward with pulses being sent from the vessel which bounce off the ocean floor then return to the vessel.
Typically finely wrought ocean maps have been the result of extensive sonar.
