How changes in temperature create ocean currents ( Ocean Stratification Demonstration)

The ocean has many currents underneath the surface. One way these currents are created is by the difference in temperature of the water. Cold water is denser than warm or hot water and will flow underneath the warmer water.
This circulation of the ocean caused by changes in temperature is called Thermohaline circulation (THC)

Thermohaline circulation results as a result of differences in the density of the different temperatures of the water. These differences result in ocean stratification.


In this video, I use a container that is divided into two chambers to show how water flows.

Here are keywords you can use to order a similar container
