One group of students did an experiment to study the movement of ocean water. The steps of the experiment are listed below.

Fill a rectangular baking glass dish with water. Place four plastic bags with ice in the water at different parts of the dish. Put a few drops of ink in the water. The students did not observe the ink move on the surface of the water from one part of the dish to another because the experiment had a flaw.

Which of these statements best describes the flaw in the experiment?

Not enough ice was used.
Not enough water was used.
The dish was too small for the ink to move on the water surface.
There was no equipment to create temperature difference in the water.

there was no equipment to create temperature difference in the water
hope this helps and can i get a brainly?
btw i make deals, if thi is wrong i own you ten questions you can ask me on my pf for free and i'll do it!

Answer:

There was no equipment to create temperature difference in the water.

Explanation:

The temperature difference would create convection currents in the water causing the water to flow from the hot area to the cold area. Thus the hot water would carry the ink with it to the cold parts of the water, causing the ink to get evenly distributed throughout the water. The lack of temperature difference is the flaw in the experiment.
