Seawater is water from a sea or ocean On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, or 599 mM). This means that every kilogram (roughly one liter by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salt (predominantly sodium chloride iron: Na+, Cl−). The average density of seawater at the ocean surface is 1.025 g/gm Seawater is denser than both fresh water and pure water (density 1.0 g/ml @ 4 °C (39 °F)) because the dissolved salts add mass without contributing significantly to the volume. The freezing point of sea water decreases as salt concentration increases. At a typical salinity it freezes at about −2 °C (28.4 °F). The coldest sea water ever recorded (in a liquid state) was in 2010, in a stream under an Antarctic glacier, and measured −2.6 °C (27 °F

Is a bay fresh or salt water?
A bay is a body of water bordered on 3 sides by land, and by definition the "4th side" is the ocean. Whether it is saltwater or freshwater will depend on where the water is from. If the bay is of an ocean, it will be of saltwater. If it is of a freshwater lake or river, it will be of freshwater.
What is the similarities between hypertonic solution and hypotonic solution?
The only similarities are that these deal with solutions. If the cell is placed into a hypotonic solution, the amount of salt (or sugar) will be lower, and water will move into the cell, and it will swell. Water will move from a lower concentration of water to a higher to reach a balance. The opposite will be true for hypertonic solutions, the cell will lose water. They appear crenate or serrated.
Do anacondas live in salt water?
The natural habitat of the Anaconda is freshwater rivers and swamps in South America. Even sea-snakes indigenous to the ocean require fresh water to drink or they become dehydrated and die.It is highly unlikely that an Anaconda could survive in salt water for any significant length of time.
What affect has irrigation have on the great lakes?
Irrigation of the Great Lakes could result in Salinization. It would be turned from freshwater to salt water. All of the salt would stay while the water would be drawn out leaving mostly all salt found behind. It could end up in the lakes shrinking.
Why does the Great Salt Lake have salt but the Great Lakes don't?
The Great Salt Lake has salt because it as no outlet, the salt of thousands of years has flowed into the lake. As the water evaporates, it leaves the salt there and it increases in concentration. The Great Lakes do not have salt because they are normal lakes, mostly fed by freshwater mountain streams and rivers, with an outlet to the oceans, so the salt does not increase in levels.
