G-spotter Posted November 12, 2007 Posted November 12, 2007 New article in the latest ish of Scientific American on the effects of crustal heat fluxes on topography contains this gem: "Were it not for the effects of a cold slab of subducting oceanic plate that insulates it from the hotter mantle underneath, the average elevation of Seattle would be 1,813 meters (5,949 feet) above sea level."

builder206 Posted November 13, 2007 Posted November 13, 2007 Imagine the size of the container cranes down at the port. It would take weeks to unload a ship if you had to lift each container a mile. And how would Todd Shipyards launch a new hull, send it over a waterfall? Quote

Excellent kayaking run... and maybe we'd get some frozen WI in the winter right in our back yards... Quote

I may be wrong, but I believe the correct grammer should be "All of you spell check fuckers..." But what do I know? I'm just a chicken. COCK A DOODLE DOOOOOOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!!!!!!!!!!!!

Dru, would you care to explain this to us non-geologists? If it were not for the insulating effect, the continental plate above would be hotter, would it not? How would this lead to a greater elevation? Is it simply that warm rock is less dense and therefore would be more bouyant? Quote

E-rock Posted November 13, 2007 Posted November 13, 2007 (edited) Catbirdseat - you are considering only the density of the continental crust and any density differential that would occur due to heating. However, the entire lithospheric rock column below Seattle includes a cold, dense oceanic slab, which, if removed, would greatly increase the bouyancy of the overlying continental crust, because it is currently thinner and hotter than average continental crust. The statement in Sci-American is b.s. for a number of reasons. 1. If not for the subducting slab in the PNW - there would BE NO FUCKING MOUNTAINS. 2. Continental crust along passive margins - i.e. where there is no active subduction - is significantly cooler, often thicker, and always MORE dense than continental crust along an active margin, like the PNW. 3. If Seattle were at 5000' of elevation, the coastline would exist significantly further to the west of its current location. Continents don't drop off abruptly. If the slab didn't exist the entire make-up of the continental margin would be different. 4. If you want to know what Seattle would be like without a subducting slab, come to New York.
