Question

The formation of deep ocean currents ​

Answer 1

Answer:

As the seawater gets saltier, its density increases, and it starts to sink. Surface water is pulled in to replace the sinking water, which in turn eventually becomes cold and salty enough to sink. This initiates the deep-ocean currents driving the global conveyer belt.

Answer 2

Answer:

1 - In the Earth's polar regions ocean water gets very cold, forming sea ice. ... Surface water is pulled in to replace the sinking water, which in turn eventually becomes cold and salty enough to sink. This initiates the deep-ocean currents driving the global conveyer belts
