Question

Which of the following conditions would cause the salinity of ocean water to decrease?


A.
high rates of evaporation


B.
freezing of glaciers


C.
extremely hot weather


D.
a river flowing into the sea

Answer 1

If the temperature is hot, the water evaporates causing humidity thus leaving behind the salt making the ocean saltier. If the temperature is colder it retains the salt and spreads outs.

Answer 2

I'd say B

Answer 3

Its not B, its D, just took the same test and i got the whole test wrong because it was the wrong answer:/ @tHe_FiZiCx99

Answer 4

The answer is D for sure:)

Answer 5

Really? I took the same test and I got B as a correct answer, D would be because more water is being added.

Answer 6

So, which one is it?

Answer 7

How would it be D rivers do not hold much salt?

Answer 8

This is about the third time I have seen this.

A-Wrong, salt will not evaporate so you will decrease the water volume but maintain a constant salt amount, which will increase the salt concentration
B-Wrong, salt is forced out of water as it freezes so all the glaciers are freshwater. This causes the exact type of thing as A
C-Wrong, hot weather will increase evaporation, see A for explanation
D-Correct. Rivers are freshwater and so you will be adding in water with a lower concentration of salt. Essentially, you are adding in water at a faster rate than you are adding in salt so the relative amount of salt in the water is decreases [lower concentration].

Answer 9

its D I'm 100% sure

Answer 10

D is correct
