- The thickest ice in the world is found in East Antarctica, where the ice sheet reaches a maximum thickness of 4,800 meters (15,748 feet).
- The Arctic sea ice is much thinner, with an average thickness of only 1-2 meters (3.3-6.6 feet).
- The main reason for this difference in ice thickness is that the Arctic Ocean is surrounded by landmasses, which allows the ice to build up over time.
- In contrast, Antarctica is a continent surrounded by ocean, which means that the ice can flow away more easily and prevent the formation of very thick ice sheets.
