Question

Compared with surface currents, deep currents are a. colder and less dense. c. warmer and denser. b. warmer and less dense. d. colder and denser. Please select the best answer from the choices provided A B C D

Answer 1

Answer:

D) colder and denser

Explanation:

as the temp drops the density increases and the water at the bottom of the ocean are much colder than the surface. i also got a 100 on the quiz soooo

Answer 2

The correct answer is option d, that is, colder and denser.  

The surface currents refer to the currents at the surface of the water, to a few hundred meters deep, while deep currents refer to the currents when the density increases to a greater extent.  

The surface current takes place close to the surface and move horizontally. This kind of currents are caused by global winds, an example of surface current is Gulf Stream. On the other hand, deep current takes place in the ocean and is affected by the density of water, temperature, and salinity. An example is Antarctica Bottom Water. In comparison to surface currents, deep currents are colder and denser.
