Icebergs are blue or green

iceberg: iceberg types. Art. Encyclopædia Britannica Online.

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:

  1. The term “iceberg” refers to chunks of ice larger than 5 meters (16 feet) across.
  2. It is one word
  3. Smaller icebergs, known as bergy bitsand growlers
  4. The word “iceberg” is a partial loan translation from Dutch ijsberg, literally meaning ice mountain
  5. Icebergs shedding is called “caving”
  6. People surf  iceberg waves created by “caving”.
  7. 1/9th of an iceberg is outside of the water because of the density
  8. 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:

  1. Glacier. any large mass of ice that originates on land by the recrystallization of snow or rain
  2. 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
