Yes, glaciers are composed of fresh water. Glaciers form from the accumulation of snow over many years, which compresses into ice. Since the snow originates from atmospheric water vapor, it is inherently fresh and free from salt. This makes glaciers one of the largest reservoirs of fresh water on Earth.
Glaciers store about 69% of the world’s fresh water. As they melt, they release this fresh water into rivers and lakes, which can be a vital source of drinking water for many communities. However, the melting of glaciers due to climate change is a growing concern, as it can lead to rising sea levels and the loss of this crucial fresh water resource.
