Rise of Earth's crust - post-glacier

Isostatic rebound is when the land rises up out of the sea due to the weight that is no longer keeping it down.

Alaska is a land of extremes.  I've been to Barrow, Alaska where the rising sea level due to climate change has completely wiped away their old highway and had to be replaced with a new one.  And I've been to Glacier Bay where just 200 years ago the entire National Park would've been under millions of years-old ice.  The ice is melting so fast soon there will be a new connection to Canada.

The interesting thing is that after all this ice melted off the land; the land is springing up.  An inch and a half a year (http://www.npr.org/templates/story/story.php?storyId=91894873). 

My question is this: how would gravity affect the land and how would an UA earth affect the land?  Same outcome?

I'll write my opinion soon.

Because of the equivalence principle, you aren't going to be able to discern any difference between gravity and UA. That's how they get away with it.

Yeah I realized that.

I was thinking of a sponge cake in a seat of a car with a fat woman sitting in front of it.  Becuase of the G's the sponge cake will get squished in between the seat and fat woman.  Then when the fat woman sees cheesy potatoes on the floor and dives down the sponge will free itself.
