A tunnel under the Atlantic?

trench? ... it's a ridge ... they are kinda opposite

[klenke]

It's a spreading center--a "trench" in the middle with raised lateral ridges on either side + transverse fault ridges (perpendicular to the trench).

The topography you see in your cartoon earth science diagrams is vastly exaggerated.

He means the aspect ratio is exaggerated for effect.

I'm glad to see so many people paid attention during their earth science classes. Did my thesis on mid-ocean ridges. :-)

So, foraker, give us your expert analysis on the issues faced for putting a tunnel through the Mid-Atlantic Ridge. If anyone would know, seems like it would be you.

weak. trenches are subduction zones like the marianas trench. the ridge is not a trench...just the opposite. in fact iceland is part of the mid atlantic ridge
