Actually, they do melt and they move around.

The Southern Ocean, surrounding Antarctica, contains a large number of icebergs due to the region's vast ice sheets and glaciers. These icebergs often break off from the continent's ice shelves and float into the ocean.
They do. It just a slow process.
After breaking off a glacier or ice sheet, icebergs can float in the ocean and drift with ocean currents. They may eventually melt, break apart further, or run aground. Some icebergs may also pose a hazard to ships navigating in the area.
Certainly when the sun turns into a red giant. Prior to that no one can say with certainty.
Icebergs float north until they melt completely.
The temp of the ozone layer has no affect on icebergs.
No, they are largest near the continent where the calve off. As they float in sea water, they melt and become smaller, regardless of where they are located.
Most free icebergs (no longer attached to ice shelves or glaciers) will have melted within five years. There will still be ice cover on Greenland, Antarctica and high mountains in five years.
Yes there are many Ice bergs in Antarctica.
Icebergs.
Antarctica. Further information: Whilst it is true that you can see icebergs in Antarctica all year long, Antarctica is a continent, not a country. Iceland has ice all year round, and icebergs are evident even in Summer.
Antarctica is a continent, and continents do not 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.
Since calved-off icebergs from Antarctica contain pure water without any minerals, if it were technically possible, pure water could be harvested from icebergs. However, no one has devised that technology to date.
