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.
Ice shelves form when glaciers reach the sea and begin to float. The Ross Ice Shelf in Antarctica is a famous ice shelf. Chunks of ice can break off an ice shelf or a glacier that reaches the sea. This is called calving.The ice chucks form icebergs up to 250 km long and 100 km wide.Very small icebergs are called bergy bits. When a glacier melts, all of the rock, sand and mud that it was carrying gets left behind. Geologists call this mixture of sediment till.he ice chucks form icebergs up to 250 km long and 100 km wide.
