Explanation:
The ocean conveyor belt explains the cyclic nature of global water round the globe.
It suggests that cold denser water circulates and moves downward whereas warm water rises.
- The great ocean conveyor belt shows that the world's ocean is constantly circulating and mixing.
- At high latitude where temperature is low, warm water from around the equator where the sun is over head loses heat to warm the atmosphere.
- As they lose heat, they become colder and denser.
- They then sink and begin to flow southward where they get heated and rise.
- This conveyor belt is driven by salinity and temperature differences.
