Icebergs.
The icebergs that break off do so because the glacier of which they are a part flows toward the sea, like a river, only much slower.
When a fracture or a vulnerable sheer exists in the glacier, and the glacier tongue drifts far enough into open water, and the sea currents or waves exert enough pressure on the tongue, the tongue splits off from the glacier and becomes an iceberg.
Ice shelves extend from the continent over the ocean.
Sea ice freezes in place on the surface of the ocean.
an ice sheet
The Arctic Ocean is located at the North Pole. Also a huge ice sheet.
The ice sheet holds 100% of Antarctica's . . . ice sheet.
There is no land underneath the North Pole - it lies entirely on water. The North Pole sits on a floating ice sheet which is called the Arctic ice sheet.
There are glaciers in the Arctic, but the North Pole itself is not glaciated. This is because, by their very definition, glaciers are regions of fresh water ice on land, and quite different to sea ice. The North Pole itself does not lie on any land mass, but on a floating ice sheet known as the Greenland or Arctic ice sheet - therefore, there can be no glaciers on the North Pole.
a sheet of ice is called a glacier
an ice sheet
In Canada, at least, the sheet of ice is simply referred to as a rink.
The ice covering 98% of the Antarctic continent is called an ice sheet.
The North Pole sits on a floating ice sheet which is called the Arctic ice sheet.
All of the ice that covers 98% of the Antarctic continent is called an ice sheet. Several glaciers are named, and the ice sheet is named the Antarctic Ice Sheet.

The waters of the Southern Ocean freeze around the Antarctic shores during the extreme cold and sunless winter. As opposed to the permanent ice, glaciers, and ice shelves, this sea ice extends for miles into the ocean, covering an ocean area about twice the size of the Antarctic continent (14 million km2). This ice melts again during the summer. The continent itself does not change in size, but the ice sheet that covers 98% of the continent merges with the frozen sea ice, essentially doubling the size of the ice sheet.
The process of ice breaking off a glacier or ice sheet is called "calving".
They create a white sheet of ice across the ocean ( as Far as it can without being melted by the sun
None, it is an imaginary point on the Arctic Ocean ice sheet.
The Arctic Ocean is located at the North Pole. Also a huge ice sheet.
