A student places a large pot of cold water on a stove and heats it for one minute. Then she takes the pot of water off the burner and places it on the counter. Which best describes the convection currents?

Water near the bottom of the pot is warmer and less dense, so it rises while cooler, denser water sinks. Even after the pot is removed from the burner, the water still has temperature differences, so convection currents continue moving thermal energy for a time. Choice D is incorrect because warmer water is less dense, not denser.
