"Glaciers are huge masses of ice, snow, rock, sediment, and often liquid water that originate on land and move down slope under the influence of their own weight and gravity. The two main types are continental glaciers (or ice sheets) and alpine glaciers."
"Ice sheets are masses of glacial land ice extending more than 50,000 square kilometers (20,000 square miles). There are only two ice sheets worldwide today, the Antarctic and Greenland ice sheets. They contain more than 99 percent of the land ice on Earth."
"An ice shelf is a large floating platform of ice that forms where a glacier or ice sheet flows down to a coastline and onto the ocean surface. Ice shelves play an important role in slowing the flow of ice from glaciers or ice sheets into the ocean. When ice shelves collapse, research has shown that glaciers accelerate, flowing into the ocean and adding to sea level rise."
