Explain how temperature affects the following.
the density of sea water
Sea water gets more dense as temperature goes down. So, the colder the water, the more dense it is. Increasing salinity also increases the density of sea water. Less dense water floats on top of more dense water. Near the freezing point, water expands when it heats up. Seawater too. So increasing temperature decrease the density of seawater.
Rate this question :
There is higher salinity in the northern Red Sea while lower in the southern. The northern part mainly has the Gulf of Suez water which lies to the west of the Sinai Peninsula. The water from the Gulf of Suez has a salinity of about 40 parts per thousand, owing in part to evaporation, and consequently a high density.
Salinity is low in the land-locked Baltic Sea.MHB - Geography
Salinity increases in the midlatitudinal zones.MHB - Geography
With increasing depth, the temperature of sea water decreases to a certain limit.MHB - Geography
