How much of Earth is comprised of ice?

Approximately 10% of the Earth's land surface is covered by ice, including ice caps, glaciers, and permafrost. The majority of this ice is located in Antarctica and Greenland. Additionally, there is sea ice in the Arctic and Southern Oceans, which can cover up to 7% of the Earth's surface at its maximum extent. Overall, the total amount of ice on Earth is difficult to measure precisely due to its constantly shifting and changing state.
