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.
Some glaciers flow directly into the ocean while others join to form large, thick floating ice shelves. The Pine Island Glacier, flowing at over 10,000 feet per year, is believed to be the fastest Antarctic glacier. And the largest ice shelf is the Ross Ice Shelf, roughly the size of Texas. Snow falling on the surface does not stay on the surface, but takes a deeper journey through the ice sheet as it is buried by subsequent snow and is compressed into solid ice.
