What is included in the hydrosphere?

The hydrosphere encompasses all the water present on Earth, which includes water in various forms such as liquid, solid (ice), and gas (water vapor). This includes oceans, rivers, lakes, groundwater, and glaciers. Recognizing that the hydrosphere plays a crucial role in the Earth's systems is essential, as it interacts with other spheres such as the atmosphere and lithosphere.

Water, in its diverse forms, is fundamental for life, climate regulation, and many geological processes. Therefore, understanding that the hydrosphere includes every body of water on Earth, not just certain types or locations, solidifies the comprehensive nature of this concept.
