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
Here are some facts about icebergs:
- The term “iceberg” refers to chunks of ice larger than 5 meters (16 feet) across.
- It is one word
- Smaller icebergs, known as bergy bitsand growlers
- The word “iceberg” is a partial loan translation from Dutch ijsberg, literally meaning ice mountain
- Icebergs shedding is called “caving”
- People surf iceberg waves created by “caving”.
- 1/9th of an iceberg is outside of the water because of the density
- Most icebergs are salt-free water caused by mainland glaciers. Some sea-water icebergs do exist – they are green.
Because some icebergs come from Glaciers.. it is worth mentioning a little about them:
- Glacier. any large mass of ice that originates on land by the recrystallization of snow or rain
- Glaciers are classifiable in three main groups depending on their movement:
(1) glaciers that extend in continuous sheets, moving outward in all directions
(2) glaciers confined within a path that directs the ice movement are called mountain glaciers;
(3) glaciers that spread out on level ground or on the ocean at the foot of glaciated regions are called piedmont glaciers or ice shelves
