When air rises, it expands and cools, which causes its density to decrease. Conversely, when air descends, it compresses and warms, which causes its density to increase.
The density of seawater increases due to an increase in salinity (amount of dissolved salts), decrease in temperature, and increase in pressure. These factors lead to a higher concentration of molecules in the water, making it denser.
When temperature increases, density generally decreases. This is because as temperature rises, particles gain more energy and move faster, causing them to spread apart and decrease in density.
The density of air decreases with an increase in height due to the decrease in pressure and temperature with altitude. As you go higher in the atmosphere, there are fewer air molecules present, leading to lower air density.
Seawater denssity will increase as salinity increases. A less significant increase can result from temperature variations (colder is denser until freezing starts). Even smaller changes would occur with depth as the seawater is slightly compressible. As density is measured as mass/unit volume local gravity does not enter into the process.
The density of water increase after evaporation.

During evaporation the density increase.
The density of the water increases.
The density of water increase from 100 oC to 4 oC (here is a maximum); after this temperature the density decrease.

As temperature increases, water molecules gain energy and move faster, causing them to spread out and increase in volume, resulting in a decrease in density. Conversely, as temperature decreases, water molecules slow down and come closer together, leading to a decrease in volume and an increase in density.
