Salinity of water increase by evaporation.
Evaporation increase with the increase of temperature and decrease of pressure..
Water being evaporated, the concentration of salt increase and as a consuquence the density increase.
A. It increases the evaporation of water. (APEX)
Because the salt doesn't freeze out with the ice. This leaves the sea water saltier, hence more dense.
evaporation and freezing of sea water
an increase in evaporation
The density of water increase after evaporation.
After evaporation the concentration of salts increase.
The density increase after evaporation.
The concentration of solutes increase after evaporation.
Processes that increase the density of seawater include evaporation, which removes water and concentrates the salt content. This increased salinity makes the water denser. Other processes that can increase seawater density include cooling and the formation of sea ice.
