Their health is measured by mass balance and movement patterns, with significant retreat noted since the Little Ice Age. Erosion creates various geological features, while meltwater contributes to landform development.

It categorizes glaciers into continental and alpine, explaining their erosive processes like abrasion and plucking that shape valleys and produce unique landforms such as U-shaped valleys and cirques.

It notes that 97% of Earth's water is saltwater, with just 3% fresh water, mainly as ice. The hydrologic cycle, driven by solar energy, moves water through evaporation, condensation, and precipitation. Concerns about groundwater overuse and the importance of water conservation policies are addressed.
