Hydrosphere clearly distinguishes our planet from others, as almost two-thirds of the Earth is covered with water. However, not all water is available to us. The water below the water table cannot be made available for human use. Further, all available water is not fit for drinking purposes.
97.5% of Earth’s water is seawater and thus salty, leaving only 2.5% fresh water. Within 2.5%, nearly 70% is frozen, and only 30% is underground. The frozen part of the hydrosphere consists of glaciers, ice caps, and icebergs. This part of the hydrosphere is called the cryosphere.
