What are the three main ice shelves in Antarctica?
Ice shelves are common around Antarctica, and the largest ones are the Ronne-Filchner, Ross and McMurdo Ice Shelves. Ice shelves surround 75% of Antarctica’s coastline, and cover an area of over 1.561 million square kilometres (a similar size to the Greenland Ice Sheet).
What are the names of the 4 ice shelves in Antarctica?
The Larsen Ice Shelf actually comprises four ice shelves; Larsen A, on the north-eastern Antarctic Peninsula, Larsen B, south of Seal Nunataks (Larsen A and B have both collapsed), Larsen D, the large currently remaining ice shelf, and Larsen D, the long, thin ice shelf fringing the south-eastern Antarctic Peninsula.
What are some of the ice shelves in Antarctica?
Antarctica’s major ice shelves:
- Ross (472,960 km2)
- Filchner-Ronne (422,420 km2)
- Amery (62,620 km2)
- Larsen (48,600 km2)
- Riiser-Larsen (48,180 km2)
- Fimbul (41,060 km2)
- Shackleton (33,820 km2)
- George VI (23,880 km2)
What are the 2 ice shelves?
Today, there are only two ice sheets in the world: the Antarctic ice sheet and the Greenland ice sheet.
What is the largest ice shelf in Antarctica?
The Ross Sea ice shelf
The great ice sheets spill out to sea as floating ice-shelves and ice-tongues, which routinely calve massive icebergs into the waters around Antarctica. The Ross Sea ice shelf is one the largest ice shelves in the world.
How many ice shelves does Antarctica have?
300 ice shelves
There are approximately 300 ice shelves around Antarctica. Together they cover around three quarters of the Antarctic coastline – roughly the same area as the entire Greenland Ice Sheet.
What are the 5 glaciers in Antarctica?

Where is A-76 iceberg now?
the Weddell Sea
It now floats in the Weddell Sea.
Where is the deepest ice?
Antarctica
The deepest ice core records come from Antarctica and Greenland, where the very deepest ice cores extend to 3 kilometers (over two miles) in depth. The oldest continuous ice core records extend to 130,000 years in Greenland, and 800,000 years in Antarctica.
How long will Antarctica last?
If the ice sheet were to melt completely–a process that could take as little as 500 years according to some models–global sea levels could rise by as much as 20 feet, inundating islands and coastal areas worldwide. The debate over whether the ice sheet is at risk hinges partly on its past history.

Where is the largest glacier in the world?
Antarctica’s
The largest glacier in the world, Antarctica’s Lambert Glacier, is one of the world’s fastest-moving ice streams. (Ice streams are parts of an ice sheet that move faster than the sheet as a whole.)
