The two changes would decrease the density of ocean water -
- A. increasing its temperature
- D. Decreasing it's salinity
Density
the measure of a material's mass (e.g. grams) divided by its volume
- There are two main factors that affect the density of ocean water : temperature and salinity.
- Cold, salty water is denser than warm, fresher water
- Cold salty water will sink below the less dense layer.
- Ocean water gets denser as the temperature goes down. So, the colder the water, the denser it is.
- Increasing salinity also increases the density and vice versa, of sea water because the mass of the water increases
Thus,
The two changes would decrease the density of ocean water -
- A. increasing its temperature
- D. Decreasing it's salinity
