NASA finds rectangular iceberg in Antarctica

The video discusses a tabular iceberg photographed over Antarctica, believed to have fractured from the Larsen Sea Ice Shelf. It contrasts tabular icebergs, which have flat surfaces and steep sides, with angular icebergs that typically have only the tip visible. Tabular icebergs form when ice shelves grow and break off, often resulting in straight lines. Sharp corners on an iceberg suggest it is new, as wind and waves usually round them out over time.

Where was the tabular iceberg photographed?

• Antarctica

• Greenland

• North Pole

• Arctic Ocean

What is a key difference between angular and tabular icebergs?

• Tabular icebergs have steep vertical sides.

• Angular icebergs are larger.

• Angular icebergs have flat surfaces.

• Tabular icebergs have rounded edges.

What feature is common in tabular icebergs?

• Rounded corners

• Flat surface

• Pointed tip

• Curved sides

How do tabular icebergs typically form?

• By collision of smaller icebergs

• By freezing of ocean water

• By breaking off from an ice shelf

• By melting of glaciers

What indicates that a tabular iceberg is newly formed?

• Its rounded edges

• Its sharp corners

• Its color

• Its small size
