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 shelf life of dry ice depends mainly on how the dry ice is stored and the size of the brick. Dry ice is frozen carbon dioxide, the same gas that we exhale and that plants use for photosynthesis. It is never a liquid, it goes from a -109.3Â°F solid state directly into the gas stage. Because of these properties, dry ice enjoys most of its popularity at Halloween for making a fabulous witch's brew.
