Hydrosphere
The hydrosphere is the collective term for all water bodies on Earth, including oceans, lakes, rivers, groundwater, glaciers, and water vapor in the atmosphere. Covering 71% of the Earth's surface, the hydrosphere is a vital resource essential for supporting life. Water within the hydrosphere continuously cycles through processes like evaporation, condensation, precipitation, and runoff, maintaining a global water balance between the Earth's surface and atmosphere. This balance profoundly influences Earth's climate, ecosystems, and human activities.

- Hydrosphere and Gaia
The hydrosphere includes all the water bodies on Earth and is an essential component of the Gaia system. The hydrosphere interacts with the biosphere, atmosphere, and lithosphere through the water cycle, which involves processes such as evaporation, condensation, precipitation, and runoff. The Gaia hypothesis emphasizes the critical role of the hydrosphere in regulating the Earth's climate, distributing heat, and sustaining life. For example, the oceans absorb and store large amounts of carbon dioxide, influencing the global carbon cycle through the marine biological pump. Additionally, the hydrosphere affects the global climate system through ocean currents and climate patterns.
