Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
Most of Earth's surface is ocean water: 70.8% or 361 million km 2 (139 million sq mi). [97] This vast pool of salty water is often called the world ocean, [98] [99] and makes Earth with its dynamic hydrosphere a water world [100] [101] or ocean world. [102] [103] Indeed, in Earth's early history the ocean may have covered Earth completely. [104]
The entire ocean, containing 97% of Earth's water, spans 70.8% of Earth's surface, [8] making it Earth's global ocean or world ocean. [23] [25] This makes Earth, along with its vibrant hydrosphere a "water world" [43] [44] or "ocean world", [45] [46] particularly in Earth's early history when the ocean is thought to have possibly covered Earth ...
The lake covers nearly 14,000 acres (57 km 2) with 190 miles (310 km) of shoreline touching three counties. [6] The lake is an average of 23 feet (7.0 m) deep with an estimated volume of 1.35 × 10 10 cubic feet (3.82 × 10 8 m 3 ).
Strictly speaking, a sea is a body of water (generally a division of the world ocean) partly or fully enclosed by land, [4] though "the sea" refers also to the oceans. Saline water covers approximately 361,000,000 km 2 (139,000,000 sq mi) and is customarily divided into several principal oceans and smaller seas, with the ocean covering ...
If the pool is used for Olympic Games or World Championships, then the minimum depth is increased to 2 metres (6 ft 7 in). [3] Whereas the Water Cube pool used for the 2008 Olympics was 3 metres (9 ft 10 in) deep, the temporary pool used in 2024 was only 2.2 metres (7 ft 3 in), which commentators suggested made for slower race times.
In 1970, American Realty Service Corporation of Memphis, Tennessee, began the development of Lake Waynoka by buying farm land, damming the headwaters of Straight Creek, a tributary of the Ohio River, and dividing the land into lots roughly one-third of an acre in size. American Realty also created other lake communities.
