GEOLOGY

Detailed explanation-1: -Salinity, temperature and depth all affect the density of seawater. Density is a measure of how tightly a certain amount of matter is packed into a given volume. The more the stuff is packed in, the higher the density. Density can be calculated by dividing an object’s mass by its volume.

Detailed explanation-2: -Temperature has a significant effect on density but salinity does not.

Detailed explanation-3: -The density of water increases as the salinity increases. The density of seawater (salinity greater than 24.7) increases as temperature decreases at all temperatures above the freezing point. The density of seawater is increased by increasing pressure.

Detailed explanation-4: -The density of seawater depends on temperature and salinity. Higher temperatures decrease the density of seawater, while higher salinity increases the density of seawater.

Detailed explanation-5: -The temperature of ocean water varies by location – both in terms of latitude and depth, due to variations in solar radiation and the physical properties of water.
