But you may be struggling to understand some of the finer details of melting ice, such as the difference between icebergs and ice floe. An iceberg is a large mass of freshwater ice that has broken off of a glacier or an ice shelf. An ice floe is a large, flat pack of floating ice.
5 lut 2018 · Sea ice is the free-floating ice that surrounds the polar regions. Unlike icebergs, which break off from land-based ice, sea ice is created by sea water freezing. Because sea ice is less dense than sea water, it floats on the surface.
While it is true that both glaciers and ice floes are large masses of ice that can be found in arctic regions, there is a major difference between them. Basically, glaciers originate on land, and ice floes form in open water and are a form of sea ice.
29 sie 2023 · An iceberg is simply a chunk of ice that has broken off from a glacier or an ice shelf and has floated into open water.
18 sie 2022 · The difference between sea ice and ice shelves is that sea ice is free-floating; the sea freezes and unfreezes each year, whereas ice shelves are firmly attached to the land.
Once ice floes form, the water underneath becomes insulated and heat loss to the atmosphere declines, so the water no longer cools and no more ice formation occurs. As a result, young sea ice is usually relatively thin, not more than 3-4 m thick.
Sea ice forms, grows, and melts in salty ocean water. This sets it apart from other forms of ice like icebergs, glaciers, and lake and river ice. Icebergs and glaciers form from snow falling on land. Lake and river ice from fresh water.
