Answer

Brief Explanations:

Icebergs are large chunks of ice that break off from glaciers or ice shelves which are large ice - sheets found at the poles. Seawater freezing forms sea ice which is different from icebergs. Groundwater freezing does not form icebergs. And while Iceland has glaciers, 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.
