Oceanography: Deep Currents

The video explains how deep ocean currents are influenced by water density differences. Cold, salty water at the poles is denser and sinks, creating deep currents that flow towards the equator. This concept is demonstrated using a tank where cold, dense water moves beneath warmer, less dense water.

What happens to cold salty water at the poles?

Explain how the flow of ocean currents is related to the equator.
