It depends on a number of things, including:
1) How big they are when they calve
2) How cold the iceberg's internal temperature
3) How quickly they are transported to warmer water
4) How warm the water around them is
5) How warm the air around them is
6) How calm the water around them is
Small ice bergs that move rapidly into warm waters probably won't last a week. On the other hand, large icebergs that remain in polar waters might take over ten years to melt.
Yes, they always melt. They absorb thermal energy (as in heat) which will cause it to heat up and melt little by little. I'm not sure this is true. Large icebergs usually break up before they melt, so, technically, they don't melt. It's the smaller ice bergs that melt. The "large icebergs" cease to exist at the point when they break up, so they don't last long enough to melt. Also, some large icebergs end up fusing back into the glacier they calved from. These icebergs cease to exist at that point, before they ever had a chance to melt. One way or another, every iceberg will, eventually, cease to exist. But it's not always by melting.
Icebergs melting adds fresh water to the oceans. Icebergs are floating already, so when they melt they do not cause a rise in sea levels. Glaciers and land ice, like the Greenland ice-cap, and any ice on Antarctica, do cause a rise in sea levels when they melt.
No. Icebergs are in the water already, so their melting does not raise sea levels.Glaciers and land ice when they melt do raise the sea levels.
well the temperature of the earth is rising, and since icebergs are pretty much big chucks of frozen water, when they melt were stuffed 'cause it'll end up with probably half the earth underwater
in green land and Antarcticasomewhere in the south pole'Another AnswerIcebergs are calved off permanent glaciers, which you can find in the high latitudes in both hemispheres. All icebergs, by definition, float in sea water. As the bergs float into warmer water, they melt.
Icebergs float north until they melt completely.

Actually, they do melt and they move around.
The temp of the ozone layer has no affect on icebergs.
Due to global warming, the icebergs are melting. If the icebergs melt, the ploar bears will become extinct due to the fact that many of them live on icebergs.
The plural of ice is ices. As in "eat your ices before they melt".
Quite simple. They dont move. They melt.
I don't think you and I have much choice in the matter. They melt on their own as the move to warmer waters.

Icebergs are the only freshwater part of an ocean. When icebergs melt, it results in a decrease in the salinity of ocean water.

I am not sure that anybody actually does it, but I read a proposal to tug icebergs to hot dry places and melt them down for a fresh water supply.
