The largest hydrologic compartment containing fresh water is ice caps and glaciers, storing about 68.7% of the world's fresh water. This frozen water plays a crucial role in regulating global climate and sea levels.
The Antarctic ice sheet contains about 90% of earth's ice.
The world's largest group of freshwater lakes is the Great Lakes, located in North America. They consist of Lakes Superior, Michigan, Huron, Erie, and Ontario, and together make up one-fifth of the world's surface fresh water.
