The total volume of water on Earth is estimated at 1.386 billion km 3 (333 million cubic miles), with 97.5% being salt water and 2.5% being freshwater.Of the freshwater, only 0.3% is in liquid form on the surface.
The combined volume of water in all the oceans is roughly 1.335 billion cubic kilometers (1.335 sextillion liters, 320.3 million cubic miles). [ 72 ] [ 91 ] [ 92 ] This section is an excerpt from Hydrosphere .
This article lists lakes with a water volume of more than 100 km 3, ranked by volume. The volume of a lake is a difficult quantity to measure. [1] Generally, the volume must be inferred from bathymetric data by integration. Lake volumes can also change dramatically over time and during the year, especially for salt lakes in arid climates.
A cubic mile (abbreviation: cu mi or mi 3 [1]) is an imperial and US customary (non-SI non-metric) unit of volume, used in the United States, Canada and the United Kingdom. It is defined as the volume of a cube with sides of 1 mile (63360 inches , 5280 feet , 1760 yards or ~1.609 kilometres ) in length .
Though the smallest of the Great Lakes by surface area, Lake Ontario holds an amazing 393 cubic miles of water. Those depths host a variety of native and nonnative aquatic life as well as birds.
Earth's approximate water volume (the total water supply of the world) is 1.386 billion cubic kilometres (333 million cubic miles). [24] Liquid water is found in bodies of water, such as an ocean, sea, lake, river, stream, canal, pond, or puddle. The majority of water on Earth is seawater. Water is also present in the atmosphere in solid ...
Lake Erie is the shallowest of the Great Lakes but bests its cousins in several other ways. Find out more about all the Great Lakes.
At any given time, about 2 × 10 13 tonnes of this is in the form of water vapor in the Earth's atmosphere (for practical purposes, 1 cubic metre of water weighs 1 tonne). Approximately 71% of Earth's surface, an area of some 361 million square kilometres (139.5 million square miles), is covered by ocean .
