Verified step by step guidance

Understand the distribution of Earth's freshwater: Freshwater is distributed across various reservoirs including glaciers, ice caps, underground aquifers, rivers, lakes, and the atmosphere.

Identify the largest reservoir of freshwater: Glaciers and ice caps hold the majority of Earth's freshwater, accounting for about 68.7% of the total freshwater supply.

Consider the role of underground aquifers: These are significant sources of freshwater, but they contain less than glaciers and ice caps, approximately 30.1% of the total freshwater.

Evaluate the contribution of rivers and lakes: These bodies of water contain a very small fraction of Earth's freshwater, around 0.3%.

Acknowledge the presence of freshwater in the atmosphere: The atmosphere holds a minimal amount of freshwater compared to other sources, primarily in the form of water vapor.
