[edit] Questions

Moving away from the mid-ocean ridge, ocean depth progressively increases until it reaches ocean trenches.

That's not always true. Atlantic ocean basin has passive margins, most of it has no subduction zones. Siim 18:41, 28 August 2005 (UTC)

The area around the mid-ocean ridge is dominated by volcanic basalts

What is volcanic basalt? Siim 18:41, 28 August 2005 (UTC)

[edit] Removed section

I removed this section, mainly because I don't quite know how to clean them up.

The process responsible for the formation of new mid-ocean ridges (the transition from rift valley to mid-ocean ridge) is not fully understood, however the Red Sea is an example of where the Gulf of Suez to the north is though to represent the earliest stages of the mid-ocean ridge seen in the Southern Red Sea. Similarly, the northern Red Sea is thought to show the stage in between the Gulf of Suez and the Southern Red Sea.

If anyone can figure out what they mean, exactly, feel free to replace them. -- Joyous! | Talk 04:40, 5 June 2006 (UTC)

[edit] Inconsistency in movement rate

There is an inconsistancy betweeb this page and the one on mid-Atlantic ridge - this page says the movement is 10mm per year (each side?) and the mid-Atlantic page says the Atlantic is growing by 50-60mm year. Any one know the right figure?

North Atlantic 10 mm whereas south Atlantic is the faster rate. The whole ridge is not spreading at a fixed or constant rate. Don't see a reference for either number though. Vsmith 11:34, 18 August 2006 (UTC)
