that is only for ice that is floating in water, numb nuts.

what about ice sitting on land, like on greenland and antarctica? did you think of that? did you even bother reading the thread?

Would water level not drop slightly?

based on what he said, no. Its the ice on land that we have to worry about. When those ice melt, it will cause the world's ocean level to rise somewhat.

Maybe that water can be funnelled into Georgian Bay somehow.......

Yeah, Im a numb nuts.. why dont you learn to read.... I specifically said 'to the people saying ice in glass of water = overflow....'

Yes, but in this case, the glass of water wouldn't be a glass of freshwater... it'd be a glass of seawater which has a higher density. Thus, when the ice melts, it will overflow a little tiny amount.

No, you're both wrong.

Unlike most materials, ice is less dense than water. If you melt an ice cube, the water will take up more volume than the ice.

If the ice at the north pole melted, the ocean levels would rise.

Edit: Oops, I had that ass backwards. Yes, if you melt an ice cube, the water will take up LESS volume

Discuss.

Because glaciers are on dry land. See Antarctica, Greenland for example.

You need to stop and realize that you have no idea what you're talking about. Thanks

Seriously, do the experiment yourself. Fill a bucket with ice cubes, and then fill it to the brim with water. Allow the ice to melt and observe that the water level stays about the same or even goes down

It's a fluke in the way water freezes. It forms a crystalline structure that essentially spaces out the molecules. Ice takes up more volume than an equal mass of liquid water.

No, it wont, it just means that while the ice is still in a block it will float a bit higher because it wont have to displace as much volume to float.

You might want to re-examine your logic. You are saying that ice has more volume and is less dense than the water is contains. Than why would you get more volume when it melts, overflowing its container?

Would it not revert back to its water state, thus becoming more dense, thus taking up less volume, thus not overflowing, but actually dropping the level?

LOL!!! Im not even going to respond to this one... on a side note, dont you hate it when you fill up your ice-cube tray to the brim and all you get is little ice pellets? Or when you freeze a bottle of water and it shrinks the bottle..

Seriously, do the experiment yourself. Fill a bucket with ice cubes, and then fill it to the brim with water. Allow the ice to melt and observe that the water level spills over the sides of the bucket.

Lol, take your own advice

You have no clue... if a bucket is brimming with a mix of water and ice in it, there is no sudden explosion of water out of the bucket when the solid changes state to liquid... The water level will remain constant.

This thread makes me feel sorry for humanity, the school systems, and my wee wee.

Aside from that, I'm safe because I have a submarine as well as an old missile silo evil genius base hidden away in the rocky mountains.

The actual issue here, as others noted, is that the ice in question currently rests on land above sea level. So if it melts, it would be like adding water to an already full glass. It has nothing to do with unique qualities of H2O, of which you have contradicted yourself on here several times.

Yes, we all know that H2O, unlike every other compound in the universe, expands when it freezes and shrinks when it melts.

Actually, if you were to artificially keep the ice cubes below the water's surface, the water level would slightly decrease. The solid ice takes up more volume before it melts.

I don't think anyone can disagree with this and no one disagreeing with the fact that frozen water has lower density than liquid water. However, (given a nice physics model with no details like salt water vs freshwater), a free floating block of ice in finite amount of water when melted, well not cause the water level to change. (assuming the container of the water remains the same size and no evaporation etc....)

Yes, that is correct. It's like taking a full container and then dumping more water into it, since the ice on the south pole actually rests on a land mass. I had it mostly right until for some reason I thought that melting an ice cube would result in more water than it took to freeze into the cube :confused:

SOLUTION: Deep sea drilling. We'll suck all of the oil and natural gas out of the areas under water and creat a large void where the melting ice can go.
