검증된 단계별 안내1
Begin by understanding the distribution of Earth's fresh water. Fresh water is crucial for life and is distributed across various sources.
Consider the major sources of fresh water: glaciers and ice caps, rivers and lakes, the atmosphere, and underground aquifers.
Glaciers and ice caps hold the majority of Earth's fresh water. These are large masses of ice found primarily in polar regions and high mountains.
Rivers and lakes contain a smaller portion of fresh water compared to glaciers and ice caps. They are more accessible but represent a minor fraction of the total fresh water.
Underground aquifers store fresh water beneath the Earth's surface. They are significant sources for human consumption but still less than the amount found in glaciers and ice caps.
