They remain frozen year-round, and they serve as sources for glaciers that feed ice into the polar seas in the form of icebergs .

WebHuronian depositional style south of the Sudbury structure appears to have been strongly influenced by the early development of transtensional extensional basins. These basins were initiated by sinistral strike-slip movement along part of a Paleoproterozoic continental margin, which later evolved into a passive margin.
