Chinese family names are patrilineal, passed from father to children. (In cases of adoption, the adoptee usually also takes the same surname.) Women do not normally change their surnames upon marriage, except in places with more Western influences such as Hong Kong.
Ice shelf. An ice shelf is a thick floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves are only found in Antarctica, Greenland and Canada. The boundary between the floating ice shelf and the grounded ice that feeds it is called the grounding line.
The continental shelf is the flooded edge of the continent-extending from the beach to the shelf break, with typical depths ranging from 130 m to 200 m. The sea floor slopes over wide shelves are 1Â° to 2Â° - virtually flat-and somewhat steeper over narrower shelves.
