Detailed explanation-1: -About three-quarters of Earth’s freshwater is stored in glaciers. Therefore, glacier ice is the second largest reservoir of water on Earth and the largest reservoir of freshwater on Earth!

Detailed explanation-2: -Rising temperatures cause mountain glaciers to melt and changes the water availability. At first, as the glacier melts, more water runs downhill away from the glacier. However, as the glacier shrinks, the water supply will diminish and farms, villages and cities might lose a valuable water source.

Detailed explanation-3: -A glacier is a large, perennial accumulation of crystalline ice, snow, rock, sediment, and often liquid water that originates on land and moves down slope under the influence of its own weight and gravity.

Detailed explanation-4: -All glaciers are made from freshwater. This is due to the way glaciers form. Snowfall, which is essentially frozen rainfall, is freshwater. Even if the water in the clouds originally came from evaporated water in the ocean, the salt is too heavy for the water to hold in a vapor form.
