# Earth's Frozen Water

Understand the cryosphere and its role in Earth's water system — the cryosphere is all frozen water on Earth (ice sheets, glaciers, sea ice, permafrost, snow cover); polar ice sheets hold about 69% of Earth's fresh water; if all polar ice melted, sea levels would rise over 65 metres; and the water cycle connects polar ice to the global system through evaporation, precipitation, and meltwater flowing into oceans
