682 - What is the significance of glaciers and ice caps in the water cycle?

Glaciers and ice caps play a crucial role in the water cycle. They store about 75% of the Earth's fresh water. Here's how they're significant:

  1. Water Storage: Glaciers and ice caps store water that melts slowly over the year, providing a steady supply of freshwater to rivers and oceans.
  2. Climate Regulation: They help regulate Earth's climate by reflecting sunlight and keeping temperatures cool.
  3. Sea Level Control: Glaciers and ice caps control sea levels. When they melt, sea levels rise, but when they grow, sea levels drop.
  4. Water Supply: They provide freshwater to communities through melting, which fills lakes, rivers, and reservoirs, supporting aquatic life and human consumption.

In simple terms, glaciers and ice caps act like huge, natural reservoirs that supply freshwater and help regulate Earth's climate.
