The largest iceberg ever recorded, Iceberg B-15, was larger than the island of Jamaica and had a surface area of approximately 11,000 square kilometers (4,200 square miles). On the other hand, Ice floe is merely an accumulation of floating ice found in Arctic regions.
Glaciers confined within a path that directs their movements are mountain glaciers, those that spread on level ground at the foot of a glaciated region are piedmont glaciers, and those that spread from a glaciated region onto the ocean are ice shelves. Ice floes, on the other hand, are made of frozen seawater.
Glaciers and icebergs are remarkable natural formations that share some similarities but also have distinct attributes. Glaciers are massive bodies of ice that form over time on land, while icebergs are chunks of ice that break off from glaciers and float freely in bodies of water.

Fast ice, or land-fast ice, refers to the large, solid ice sheets that are attached to land. The pack ice consists of the smaller, free-floating pieces of sea ice. They may have formed independently, or may have broken off from the fast ice (Figure 14.1.3). Figure 14.1.3 Fast ice (left) and pack ice (right).
5 lut 2018 · Icebergs are floating pieces that have broken off from larger ice shelves. They can be big enough to sink the Titanic or land a helicopter on, or small enough to fit into a glass. They can also come in many colors, depending on the compression of ice crystals and the presence of dirt, rock, and algae.
Together they store a volume of ice that, if completely melted, would cause global sea level to rise by around 65 metres. The ice sheets of West and East Antarctica have a combined ice volume of 26.37 million cubic kilometres, and the inland ice of Greenland around three million cubic kilometres.
