What are 2 main factors that influence density if seawater?
Temperature and salinity are the two main factors that influence the density of seawater. Colder seawater is denser than warmer seawater, while seawater with higher salinity is denser than seawater with lower salinity.
Why Seawater is typically denser than freshwater?
Seawater is denser than freshwater because it contains dissolved salts and minerals, such as sodium and chloride, which add weight to the water molecules. These dissolved substances increase the overall mass of seawater and make it denser than freshwater.
