How icebergs originate

WHEN a glacier (river of ice) reaches the sea a piece sometimes breaks off, crashes into the sea and floats.

WHEN a glacier (river of ice) reaches the sea a piece sometimes breaks off, crashes into the sea and floats.

This bit of a glacier is called an iceberg and can range in size from 6m to about 320km across.

Some are 120m above the surface of the ocean, but this is only a small part of it (called the tip of the iceberg).

The iceberg that holds the record as the biggest was seen in the South Pacific in 1956.

It was 335km wide and 96km long. - bigsiteofamazingfacts.com; wikipedia.org
