It depends what you mean:
- If you mean “what fraction of Earth’s freshwater is frozen?” → about 70% (roughly 2/3–3/4).
- If you mean “how much of Earth’s surface is covered by permanent ice/glaciers?” → only about 10% of the land area (≈3% of Earth’s total surface).
- Related fact: about 90% of the world’s ice volume is in Antarctica.
So pick 70% for freshwater, 10% for surface coverage, and 90% if the question was which fraction of the ice is in Antarctica.
