Iceberg would be a large piece of ice broken off from a glacier, bergy bit a smaller piece with only a one to four meters showing, and a growler would be less than one meter.
A glacier.
A glacier if it is on land; if it floats in the sea, it's called an iceberg.
Calving
Because the theory of Isostasy states that the crust floats over the Mantel like a large piece of ice in water, so when a large piece of the crusts deteriorates, like when a extensive glacier melts, the Earth will raise up where the large piece of Earth deteriorate.
That is usually called a glacier

well a glacier is formed when layers of ice build up over hundreds of years and form a large compact block of ice.
When a glacier or very large ice burg has a large chunk of ice break away from the main body of ice, the piece that breaks away is known as a calf.
A crevasse is a large crack in a glacier.
Any large mass of ice that moves slowly over ice is called a glacier.
A glacier is a essentially a large block of ice, but it isn't truly solid. The bottom of the glacier is in a constant state of melt. This is what allows it to "migrate." Additionally, there are lakes and rivers inside of most glaciers.
