Question
hello sir,
it would be kind of you if you could answer this question for me. the question is as follows

Quest 1. Which of the following best explains the oceanic conveyor belt
1. Zonal transport of Salinity across the global ocean
2. Meridional  transport of Salinity across the global ocean
3. Zonal transport of heat across the global ocean
2. Meridional  transport of heat across the global ocean

Answer
I'd have to go with the 2nd 2., Meridional transport of heat across the global ocean.

Meridional transport means transport north and south along a meridian. Since the polar (northern) regions are cold and the equatorial (southern) regions are warm, the replacement of the sinking cold water in the polar regions by warm water from equatorial regions induces the large scale circulation.
