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.
Most ice shelves are fed by inland glaciers. Together, an ice shelf and the glaciers feeding it can form a stable system, with the forces of outflow and back pressure balanced. Warmer temperatures can destabilize this system by increasing glacier flow speed andâmore dramaticallyâby disintegrating the ice shelf.
