How big is the Arctic ice cap?
It covers an area of about 14.6 million km2 and contains between 25 and 30 million km3 of ice. Around 70% of the fresh water on Earth is contained in this ice sheet.
How tall are the ice caps?
The ice sheet is almost 2,900 kilometres (1,800 mi) long in a north–south direction, and its greatest width is 1,100 kilometres (680 mi) at a latitude of 77°N, near its northern margin. The mean altitude of the ice is 2,135 metres (7,005 ft)….

How small are the ice caps?
Ice caps are miniature ice sheets. Like icefields, ice caps cover less than 50,000 square kilometers (19,300 square miles). Unlike icefields, ice caps completely blanket the underlying land features.
How thick is Arctic pack ice?
Currently, 28% of Arctic basin sea ice is multi-year ice, thicker than seasonal ice: up to 3–4 m (9.8–13.1 ft) thick over large areas, with ridges up to 20 m (65.6 ft) thick.
How thick is the Antarctic ice cap?
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.
How big is the Antarctic Ice Sheet?
5.4 million square miles
The Antarctic Ice Sheet extends almost 14 million square kilometers (5.4 million square miles), roughly the area of the contiguous United States and Mexico combined. The Antarctic Ice Sheet contains 30 million cubic kilometers (7.2 million cubic miles) of ice.
What is ice caps short for?
In glaciology, an ice cap is a mass of ice that covers less than 50,000 km2 (19,000 sq mi) of land area (usually covering a highland area). Larger ice masses covering more than 50,000 km2 (19,000 sq mi) are termed ice sheets.
What does an ice cap look like?
Ice caps tend to be slightly dome-shaped and spread out from their center. They behave plastically, or like a liquid. An ice sheet flows, oozes, and slides over uneven surfaces until it covers everything in its path, including entire valleys, mountains, and plains. Ice caps and ice fields exist all over the world.
Is Arctic or Antarctic better?
The Arctic offers breathtaking views of fjords, mountains, and glaciers, and there are more green areas with trees and vegetation than you may expect. Antarctica, which is almost totally covered in ice, has icebergs and glaciers of incredible height, without any of the vegetation the northern polar regions have.
