The map shows the global circulation pattern of ocean currents. Francesca wants to set up a model that best represents how this type of pattern is created in the ocean. Which model should they use?

• Add several drops of red food coloring and several drops of blue food coloring to water in a jar. Then place the lid on and shake the jar.

• Pour hot water that has red food coloring and cold water that has blue food coloring into a tank of water that is at room temperature. Then have a heat lamp shine on the water.
