What two factors cause differences i ocean water density

Temperature and salt concentration in ocean water cause difference in density.

Explanation:

Density is the measurement of mass per unit of a substance. Pure water without any impurities has a density of 0.998 g/ml at room temperature. The two important factors that cause changes in Ocean water density are

1. Temperature

2. Salt concentration

If we decrease the Ocean temperature its density will increase respectively. while in case of salt concentration density of ocean water will increase with higher salinity.  

integrated circuit (ic) is defined as a set of electronic circuits on one small flat piece of semiconductor material, normally silicon. a functional electronic circuit requires transistors, resistors, capacitors, inductors, etc., and the connections between them.
