A large detached piece of a glacier is called an iceberg. The process by which this happens is called calving.
There isn't really a term for a detached piece of an iceberg. See related question.
You are probably thinking of an Iceberg, which can be a very large piece of floating ice.
An iceberg is a piece of ice that has calved or broken off from a glacier, and is therefore fresh water. Pack ice (or drift ice) is frozen ocean, and therefore salt water.
Between 10 to 20 percent of an iceberg mass is above water. An iceberg is a massive piece of floating ice. Usually, approximately 80 to 90 percent of an iceberg is below sea level. A very large iceberg can be over 230 feet in height and over 738 feet in width.
Glacial erratics aren't exactly formed. They were deposited by glaciers that were moving in that area at one time. improved= Glacial erratics are exactly formed. Because a glacier is so heavy, the glacier can pluck large rocks as the glacier moves. When the rock is too heavy for the glacier to hold, or the glacier is retreating, it then deposits the rock in a place where it wouldn't usually be found. This is what an erratic is. A large piece of rock in an unusual surrounding. i hope this helps :)
The answer is "floe."flow in all direcions
An Iceberg.
A glacier is older than an iceberg, because an iceberg is a piece of ice that fell off a glacier.

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.
Lettuce tell you ;) It is a large piece of ice that has broken off a glacier where only a portion of the piece is able to be seen above water.I shall use it in the sentence:The iceberg struck the Titantic sinking it and killing most aboard!What_does_the_word_iceberg_literally_mean

It could be an iceberg, or an icefloe
