A challenge to Ray

I posted this challenge to Ray and just to see whether he will ignore it:

Ray a challenge:

If there was this Great Flood, then explain Antartica!

A simple scientific fact: Ice floats on water. If Antartica would have been flooded the massive ice-sheet of this continent would have been lifted up. As the waters receeded this sheet would have been settled down again. The antartic ice-sheet consists of about 30 million cubic kilometers of water. A cubic meter of water weights about 1000kg. 30 million cubic kilometers of water therefor weight about 30 trillion tons.
(As comparison you could coat the USA 269 meters [882 feet] high in lead with an equivalent mass)

That poses some very interesting questions.

If you lift 30 trillion tons of ice from the antartic plate it will rise again. If you lift them all of a sudden the plate will rise quite quickly again. Why does the Bible not speak of the cataclysmic seaquakes that would have followed? Noah couldn't have possible missed the tsunamis that would have rushed through the oceans.
It wouldn't just be seaquakes. If you lift such a mass all of a sudden you would also trigger volcanism of cataclysmic strenght. It seems that Noah missed the massive amounts of ash in the atmosphere too.

Another interesting fact is that the ice-sheet doesn't portray to be lifted and settled again.
What happens you you let the sea levels rise: The outer rims of the sheet recognise first what's happening and move up. This would cause at least cracks in the ice that could still be seen. (I deem it more likely that the whole sheet would shatter and not just some cracks...)
But even if the sheet got uplifted without breaking: It would need to settle again. First of all: The sheet would not settle again to exactly the place it was lifted from. Secondly: The sea would change the underground. Therefor: If the ice-sheet wouldn't break during the lift it would certainly do when settled.

So: How do you explain that the antartic ice-sheet isn't shattered?

But there is another interesting characteristic to the antarctic ice: It comes in layers.
That is because the ice forms differently during the antartic day than it does during night. Since day and night last half a year in Antartica you can count those layers backwards like you can count the rings of trees. By simple counting you find that the inland ice of Antartica is older than 100,000 years. That neither fits your creation hypothesis nor the Flood.

How do you explain those layers?
