The hydrosphere is all of Earth's bodies of water, including oceans, lakes, rivers, and even the groundwater and Earth's frozen water. The frozen water (snow, frozen ponds, glaciers, sea ice, etc.) is part of the hydrosphere but also considered a sub-sphere of the hydrosphere with its own name: the cryosphere.
The hydrosphere is impacted by several different things. Some are natural influences, but others are influenced by humans.
Some of the major hydrosphere topics include: Water Pollution, Sea Level Changes, Glacial Ice Volumes, Ocean Composition Temperature, Ocean Composition pH (acidity), Watersheds, Clean Drinking Water, etc.
