What happens to the ocean water as it moves from Antarctica to the equator is : ( B ) It becomes less dense and rises to the surface.
<h3>Concept conveyor belt </h3>
The conveyor belt is a system of oceans which transports water and propel deep current of water bodies across the globe based on the differences in water densities.
As the ocean water moves from the Antarctica to the equator the cold ocean water mixes with the warm ocean water at the equator, which makes the water less dense and rises to the surface.
Hence we can conclude that What happens to the ocean water as it moves from Antarctica to the equator is It becomes less dense and rises to the surface.
