How would the salinity of salt in the oceans be affected if the polar ice caps melted?
Answer 1:

Since the polar ice caps are freshwater, they contain very little to no salt. If the polar ice caps were to melt, it would add a large amount of freshwater to the oceans, which would mean the overall salinity of the oceans would decrease (there would be less salt for the amount of water contained in the oceans).
