Answer

Brief Explanations:

Icebergs are large chunks of ice that break off from glaciers or ice shelves (large ice - sheets) found at the polar regions. Seawater freezing forms sea ice which is different from icebergs. Groundwater freezing doesn't form icebergs. And while Iceland has ice, icebergs don't specifically break off from its coast as a general formation mechanism.

Answer:

They break off large ice sheets found at the poles.
