Icebergs are not typically associated with the continental shelf; they originate from glaciers or ice sheets that calve into the ocean, usually from land-based ice formations. However, sea ice can form over the continental shelf in polar regions, particularly during winter months. This sea ice is different from icebergs, as it forms from the freezing of seawater rather than from freshwater glaciers. Thus, while sea ice can be linked to the continental shelf, icebergs are generally not.
Chunks of continental glaciers that break off from the edges of the ice sheets produce icebergs. These icebergs can drift in the ocean and pose a hazard to navigation.

The Ross Ice Shelf is located in Antarctica. It is the largest ice shelf in Antarctica and is about the size of France.
Icebergs form when chunks or slabs of ice break off of a glacier. They can also form when chunks of ice break free from an ice shelf.

Accumulation of snow on an ice shelf can cause the ice shelf to grow in size and thickness over time. This can increase the weight of the ice shelf and potentially lead to calving events, where pieces of the ice shelf break off into the ocean as icebergs.

Over millennia, ice builds up on land, which slopes into open water. Over time, gravity forces the ice to flow downhill into the water. A ice shelf is formed because the water's wave action has not broken off the ice to form icebergs.
Any of the northernmost or southernmost oceans and seas. How far north or south will depend on the time of year. Icebergs are found in very cold Arctic and Antarctic regions, into which the icebergs drift when they detach from an ice pack, ice shelf, or glacier.
The Ross Ice Shelf is located in Antarctica. It is the largest ice shelf in Antarctica and is about the size of France.
Icebergs are masses of ice broken off from ice sheets.
Icebergs change size and shape constantly. When a fissure or crack develops and a portion breaks off it is called a floe. Changes in icebergs are determined by climate, pressure, force and temperature.
