Question

Describe how temperature and salinity affect the density of ocean water

Answer 1

Increasing salinity also increases the density of sea water. Less dense waterfloats on top of more dense water. Given two layers of water with the same salinity, the warmer water will float on top of the colder water. ... Temperature has a greater effect on the density of water than salinitydoes.

Answer 2

Seawater is water from a sea or ocean.

On average, seawater in the world's oceans has a salinity of approximately 3.5%, or 35 parts per thousand.

This means that for every 1 litre (1000 mL) of seawater there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it.

Although a vast majority of seawater is found in oceans with salinity around 3.5%, seawater is not uniformly saline throughout the world.
