Answer 1

That is correct.
salt water has substantially higher density. The salt water immediately sinks to the bottom (so it only contacts freshwater on a small surface) and at this boundary, there is a requirement for thermal energy if the salt water is fairly concentrated, slowing the diffusion of the two.
