The hydrosphere (from Greek ὕδωρ - hydōr, "water" and σφαῖρα - sphaira, "sphere") is the combined mass of water found on, under, and above the surface of a planet.
It has been estimated that there are 1386 million cubic kilometres of water on Earth. This includes water in liquid and frozen forms in groundwater, oceans, lakes and streams. Saltwater accounts for 97.5% of this amount. Fresh water accounts for only 2.5%. Of this fresh water, 68.7% is in the form of ice and permanent snow cover in the Arctic, the Antarctic, and mountain glaciers. 29.9% is in the form of fresh groundwater. Only 0.26% of the fresh water on Earth is in easily accessible lakes, reservoirs and river systems. The total mass of the Earth's hydrosphere is about 1.4 × 10 tonnes, which is about 0.023% of Earth's total mass. About 20 × 10 tonnes of this is in Earth's atmosphere (for practical purposes, 1 cubic metre of water weighs one tonne). Approximately 75% of Earth's surface, an area of some 361 million square kilometers (139.5 million square miles), is covered by ocean. The average salinity of Earth's oceans is about 35 grams of salt per kilogram of sea water (3.5%).
