There are ice sheets which are large and blanket like which cover a lot of the ground and water. Another fact is the ice is formed into ice shelves. The shelves float in the water and are very massive. Thirdly, ice streams and outlet glaciers are another form of ice that you will see in Antarctica. They both move fast and help drain their water easily.
Ice tongues are narrow, long, and are floating.
Next, there are large icebergs which float and consistently move and melt. Lastly, sea ice freezes from sea water, but it continues to slowly melt. The above information is just part of what I have learned about Antarctica. The Ross Ice Shelf is one of the biggest Ice Shelves on the icy continent of Antarctica. The Ross Ice Shelf is more than 475 feet deep.
