If all of the icebergs in the world melted, why would it not be a problem for anyone?


What happens to the water level in a glass of water where the ice melts?

What Next?

That's dropping science!

that is not exactly right
if the material that will get out of melting ice is same as water, then you'll be right, but when salt water freezes, the salt will remain in the unfreezed water and the ice will have no salt in it, when melting the ice you'll have water, which has (i don't know what it is called but it is Mass/Volume) less then the sea water, the ice displaces sea water that has the same mass of the ice, when the ice will melt it will still have the same mass , now the question is: which has a bigger volume a certain mass of sea water or the same mass of normal water ??? the answer is normal water has bigger volume, so when the icebergs melts the level of water in the world will get higher

ST is correct here. You also have to consider that there are a lot other adverse affects (global climate shift, ecosystem destruction) that come into play besides water level.

captob, I never mentioned global warming, it was just a catchy title. Also, you left the salt water out of the equation. You never accounted for it again.

Water also expands when its heated up (an unusual property - it both expands on freezing and after melting on its way towards boiling)
Also a Hugh amounts of Ice from ice bergs are above sea level

ok, I'm going to try this: I will fill a cup with cie and salt water, and I will check after the ice has melted if the water has overflown. Expect my results later today.

I just finished teh check and salt did not affect the water level after the ice melted.

oh well waterworld is still a good movie

100% origional!

I think it would be a problem for almost all the life of this planet. It would not flood the planet but it would cause many other ecological problems.

Water has its maximum density at 4 degrees C. Since ice floats in water, it is clearly less dense than the water (salt or otherwise). The iceberg displaces the same Mass of water as itself but some of it (1/6) is sticking out of the water. Thus when the iceberg melts, it will replace its own mass (weight) in water but this will have a greater volume when and if it warms up.

This question only applies to icebergs floating in water. I don't know the exact number, but the majority of fresh water on the planet is located in Antarctica, which is a continent. If all that ice melts, it will flood the planet since it is not displacing any water.

All ice bergs DO melt. Just not all at the same time.

good job! thanks

About the ice on Antartica, if it melted you would have "Waterworld", but that isn't icebergs, icebergs are only found floating in water (by definition), and doesn't apply to the question.

By the way the book Blind Waves is more realistic than Waterworld, the seas only rise 100ft. sinking 2/3 the planet.

Mass/Volume is called Density

Ur wrong!!!!!!!!!!!!! The ice contains water and so? what if it does expand? It still adds water to the oceans on earth and some of that water must go somewhere like to the equator, expanding in the heat. WATER LEVEL WILL DEFINITLY RISE!!!!!!!
