What are continental ice sheets?
A continental ice sheet is a vast expanse of ice which completely covers all underlying terrain. They form on land and spread outward in all directions.

The Antarctic ice sheet is about 2 kilometers (1.2 miles) thick.
What is the biggest ice shelf in the world?
The Ross Sea ice shelf The Ross Sea ice shelf is one the largest ice shelves in the world. It is the size of France, and though the 200-foot-tall cliffs of ice extend 500 miles, that is just, as they say, the tip of the iceberg. Most of the ice lies hidden below the cold, dark salt water.
Where is the thickest ice sheet?
Antarctica At its thickest point the ice sheet is 4,776 meters deep. It averages 2,160 meters thick, making Antarctica the highest continent. This ice is 90 percent of all the world's ice and 70 percent of all the world's fresh water.
Where is the Greenland Ice Sheet?
The Greenland Ice Sheet is the largest ice mass in the Northern Hemisphere. It lies from 71°N northwards, between the Atlantic and the Arctic Ocean (1). Almost 80% of Greenland's landmass is covered by the ice sheet, expanding an area over 1.7 million km2.
Where is the largest ice sheet?

It covers more than 14 million square kilometers (5.4 million square miles) and contains about 30 million cubic kilometers (7.2 million cubic miles) of water.

What is the largest ice shelf in the Arctic?
1). The Ward Hunt Ice Shelf (WHIS) is the largest remaining Arctic ice shelf, with an area of ∼400 km2 (6). Disintegration of northern ice shelves has paralleled large reductions in Arctic Ocean ice that have led to the conjecture that ice-free conditions are possible in the near future (7–9).

According to Britannica, an island is a mass of land that is both “entirely surrounded by water” and also “smaller than a continent.” By that definition, Australia can't be an island because it's already a continent.
