Elliott wants to set up a model that best represents how the type of pattern shown in the global circulation of ocean currents diagram is created in the ocean. Which model should he use?

• Add red food coloring to one end of a tank of water and blue food coloring to the other. Then allow a fan to blow across the surface.

• 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.

• Slowly pour hot water that has red food coloring into a tank of water that is at room temperature. Then quickly pour cold water that has blue food coloring into the tank.

• 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.
