Processes that increase the density of seawater include evaporation and _____.
Elena L [17]
Correct Answer: option C: Formation of sea ice

Reason: 
<span> In cold regions, changes in salinity alters the water present in ocean. Further, water density also changes with temperature. In general, water density in ocean water increases with decreasing temperature. This is because,  when salt is ejected into the ocean as sea ice forms, the water's salinity increases. Since, salt water is heavier, the density of the water increases.</span>
