Iceberg

An iceberg is a large piece of freshwater ice that has broken off a glacier or an ice shelf and is floating freely in open water.

The size of icebergs varies widely. Small bergs (a littler smaller than a car) are known as “growlers” , while slightly larger bergs (about the size of a house) are called “bergy bits”. To be classified as an iceberg, the height of the ice must be greater than 16 feet above sea level and the thickness must be 98-164 feet and the ice must cover an area of at least 5,382 square feet.

Icebergs are also classified by their shape. Tabular icebergs have steep and flat tops like a plateau, while non-tabular icebergs include irregular shapes such as rounded tops, spires, sloping sides, and blocks. Wind and water erode icebergs into amazing sculptural shapes.
