What comprises the hydrosphere?

The hydrosphere encompasses all the water found at and near the surface of the Earth. This includes water in oceans, rivers, lakes, glaciers, and even in the atmosphere as water vapor. The hydrosphere is critical for sustaining life and plays a vital role in Earth's climate and various geological processes.

Understanding the hydrosphere is essential, as it interacts with other spheres such as the atmosphere (air), lithosphere (land), and biosphere (living things). The presence of water in different forms facilitates processes like evaporation, condensation, and precipitation, thereby influencing weather patterns and ecosystems globally.
