What shapes do icebergs come in?
Icebergs come in a vast array of shapes due to melting and breaking. Although no two icebergs are exactly the same, there are categories of shapes that are used for observation.
A flat-topped iceberg with a width five times greater than its height. Most have some horizontal banding.
A flat-topped iceberg with steep sides.
A flat surfaced iceberg with steep surfaces on one side and gradually sloping on the other, thus forming a wedge.
An iceberg that is smooth with a rounded top.
An iceberg with at least one main spiral or pyramid on it.
An iceberg with a U-shaped slot at or near water level, and at least two pinnacles or columns.
