Icebergs melting have no effect at all on sea levels. Ice bergs are floating ice. Floating ice displaces exactly the same volume of water as the ice itself will have when it melts, and therefore total volume does not change as ice melts. A simple experiment in your own kitchen will verify this fact.
Sea level will rise
Actually, they do melt and they move around.
melt of icebergs
Not much. Icebergs are already floating in the oceans, so any melting will not raise sea levels. Melting icebergs add fresh water to the oceans, but this will only matter if huge amounts of ice 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.
The temp of the ozone layer has no affect on icebergs.
Icebergs float north until they melt completely.
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".
I don't think you and I have much choice in the matter. They melt on their own as the move to warmer waters.
It would melt
As glaciers melt the sea level rises and cause the water to get deeper.Which comes t the theory global warming.If the theory is true the eventullay all land masses would become covered by water.
