The diagram shows the thermohaline circulation, also know as the ocean's conveyor belt.
DanielleElmas [232]

Answer:

The statement that is true about red currents in the thermohaline circulation is that  water in the red currents contain less salt (option A).

Explanation:

Thermohaline circulation is a concept used in oceanography, referring to the oceanic circulation that depends on factors such as surface heat and salinity, as well as the density gradient that they determine.

On a map, the different currents that are part of the thermohaline circulation are usually represented with blue and red lines, where:

  • <em>The blue lines represent deep, cold, dense and higher salinity currents.</em>
  • <em>The red lines represent surface currents, warm, with less salt content, so they are less dense.</em>

The red currents (see image) represented on the map have less salt content, compared to the currents represented in blue.
