Thread: fluid plate theory

Does anyone know the correct name for the theory that says the earths techtonic plates act like a fluid, they try to level themselfs out evenly, and when lower heavier parts break of into the mantle a great part of mountains that they may have been supporting will slip into the crust as it tries to level itself out.

I cant remember the name so if anyone knows that would be great. Think its something like fluid plate theory or something (hense the title) :wink:

as far as i remember its not an alternative to plate techtonics but it tries to add to it a bit more

isostasy ?

yeah isostasy sums it up. :-D

I seen a documentary on it not so long ago and they put a great emphasis on the fluid part thats why i thought fluid theory

thanks marnix ive been trying to remember the name for ages
