How glaciers act as reservoirs?

Glaciers act as natural reservoirs by storing freshwater in the form of ice, accumulating over long periods through snowfall and compacting. They release this water gradually during warmer months through melting, which helps to sustain rivers and ecosystems downstream. This process is crucial for providing water resources for agriculture, drinking, and hydroelectric power in many regions. Additionally, glaciers help regulate global sea levels and climate patterns as they store and release water.
