Question

The salinity, temperature, and density of sea water are connected. What evidence from the text supports this conclusion?

1) On average, there is a distinct decrease of salinity near the equator and at both poles, although for different reasons.
2) The temperature and salinity of the sea water also help determine its density.
3) The surface salinity is lower in the polar regions than in the tropical regions due to melting each summer.
4) The amount of salt in sea water also determines the temperature at which sea water freezes.

Answer 1

The salinity, temperature, and density of sea water are interconnected. The temperature and salinity of sea water determine its density. The amount of salt in sea water determines the temperature at which it freezes.

Step-by-step explanation:

The salinity, temperature, and density of sea water are interconnected. One piece of evidence supporting this conclusion is that the temperature and salinity of the sea water determine its density, as stated in the text.

Another piece of evidence is the distinct decrease in salinity near the equator and at both poles, which is due to different reasons. Additionally, the text mentions that the amount of salt in sea water also determines the temperature at which it freezes.
