That depends on the body of water.
Average for ocean water is approx:
1,020 to 1,029 kg•m−3
Which is only slightly more than the 1000 Kg•m−3 for pure water
Salinity (how much salt) of the water and low temperatures
The temperature of the water and the salt content of the water.
You think probable to the movement of salt waters into fresh waters.
No salt has a greater density.
Salt is extracted from salt mines or from sea waters.
The density of pure salt is 2,165 g/cm3.
Deep Currents Occurs when the density of the water increases. Density is based on two main things it is the Salinity is how much salt and other solids are in it and it is also the temperature of the water.The lower the temperature the lower the dense the water becomes. Salinity (how much salt) of the water and low temperatures.
The density of a pure salt crystal is 2,165 g/cm3. This is a true density. The density of fine powdered salt (apparent density) is variable: approx. 1 g/cm3.
Salt (NaCl) is extracted from salt mines or sea waters.
Salt is obtained from salt mines or sea waters.
Salt is extracted from salt mines or sea/ocean waters.
