Approximately 68.7% of the freshwater on Earth is frozen in polar ice caps, glaciers, and permanent snow.
Approximately 68.7% of Earth's fresh water is frozen in glaciers and ice caps. These frozen sources of water are crucial for maintaining global water cycles and sustaining freshwater availability for various ecosystems and human populations.
Around 68.7% of the Earth's fresh water is stored in ice caps, glaciers, and permanent snow. This amounts to roughly 1.7% of the total water on Earth being stored in frozen ice.
Icebergs are composed of frozen freshwater from glaciers or polar ice sheets. When they break off and float in the ocean, they are made of pure water with very low salt content.

The planet Mars has glaciers made of water ice, mostly located in its polar regions. These glaciers have been observed by orbiters and are thought to be composed of a mix of water and carbon dioxide ice.
Polar glaciers are glaciers that are frozen to the bedrock. The surface snow-pack of a polar glacier may experience melting, but the ice from the surface to the base is always below freezing.

It is in frozen form - as the polar ice caps and glaciers.
Most of the Earth's fresh water is locked up in glaciers and ice caps at the polar regions. This frozen water plays a crucial role in regulating global climate and sea levels.
Approximately 70% of the Earth's freshwater is stored in ice caps and glaciers, with about 90% of this frozen water located in Antarctica and Greenland. This means that a significant portion of the planet's freshwater resources is concentrated in polar regions. In terms of the total water on Earth, about 2% is frozen at the poles.
