its a volume of earth equivalent to taking the top five inches of every one of the United States 9.1 million square miles of land area and using it to coat the bottom of the worlds oceans. That would push sea levels up by 3.3 millimeters.
(That's .129th of an inch)
But, remember: That sea level rise happens annually. So every year, wed need to take the top five inches of the United States, roll it in a ball and drop it in the ocean to get the sort of sea level rise were currently seeing. Dont worry, though; assuming that the depth of Earths crust is about 40 kilometers in the United States, it would take 309,000 years for us to get to the mantle
And here's the idiot Congressman who said that rocks in the ocean are the real culprit:

(1,798 posts)He's right, in a way. The ice eroding/melting into water off Greenland and Antarctica is the culprit.

(22,990 posts)What, he doesn't believe icebergs and glaciers melting into the ocean displace water or add to levels?
So ignorant.

(10,036 posts)That seemed a bit odd way to put it but Ill use that as a reference point. My phone calculator is a bit limited so need to break this up a bit. Concrete is about 150 lbs per cubic foot; another approximation. So a cubic mile of concrete works out to about 22 trillion pounds. So 6600 trillion lbs (6.6 x 1000)/22 = 300 cubic miles of Stone. Actually Id have thought it would be more. Anyone want to check my math?

(14,308 posts)I live in an area where we have wicked duststorms. The whole sky turns orange sometimes and you can't even see where the road is because of all the dirt covering it.
I always assume that at some point the dirt ends up in the sea.
So over millions of years I have thought why hasn't the entire landmass eroded into the sea. Does land get replenished? I know it does through volcanoes, but that seems like such a small amount compared to the amount getting eroded into the sea each year.
Maybe the people of Hawaii would disagree with me on that right now.
Anyway, it's a question I've always wanted to ask a scientist.

After Mount St Helens devastated the plant life for miles around it, within a year there were a surprising number of new plants growing right out of the lava beds. New plant life comes back very quickly.
