Icebergs are very large in size and they can be
small as well.

How Do Icebergs Form

• How do icebergs form?Glaciers form on land as a
  result of a net accumulation of snow over
  thousands of years. Successive layers compress
  earlier accumulations until, at depths below 60
  to 70 meters, glacial ice is formed. Glaciers
  "flow" or "creep" outward under their own weight
  like a viscous fluid. When the edge of a glacier
  advances into the ocean the pieces that break off
  are what we call icebergs.

How Many Icebergs Are There

• How many icebergs are there?Approximately
  40,000 medium to large sized icebergs calve
  annually in Greenland and about 1 to 2 (400-800)
  of those make it as far south as 48o north
  latitude (St. John's). The numbers vary greatly
  from year to year and seasonally as most are seen
  off Newfoundland in the spring and early summer.

Are Icebergs Salty?

• Are icebergs salty? . Icebergs are comprised of
  pure fresh water. There may be some dust embedded
  in the ice and salt water may be on the surface
  but it does not penetrate the ice. Iceberg ice is
  quite safe to consume. No

Why Are Icebergs Mostly White?

• Why are icebergs mostly white?Icebergs are
  mostly white because the ice is full of tiny air
  bubbles. The bubble surfaces reflect white light
  giving the iceberg an overall white appearance.
  Ice that is bubble free has a blue tint which is
  due to the same light phenomenon that tints the
  sky.
