Answer 2

Do you have any guesses?

Answer 3

b maybe

Answer 4

Deep water currents are driven by the density differences in the water. Depends on the temperature and the salinity of the water. Surface water currents are driven by the wind in the atmosphere They both move from the Northern hemisphere to the southern hemisphere.

Answer 5

B is sayng that both deep into the ocean and the surface are warm thats not true the deeper into the ocean you go the colder it gets

Answer 6

so a maybe

Answer 7

We can also think this through logically, so obviously the top part of the ocean will be less dense then the bottom, so we can rule out B and D. And also we should know that the more saltier the water is, the more dense it is going down, so we can rule out B. So the only option we are left with is A, and that would make sense because it does seem a lot more warmer than lower portions of body water

Short summary - Answer A. So you are correct :]
