How is the behavior of food coloring in the cool and heated water different? What caused the differences in their behavior?
The food coloring in the cool water stayed at the bottom of the container. The food coloring in the heated water moved to the top of the container then it moved to the sides of the container. It finally sank to the bottom. Warm water is less dense and rises and cold water is more dense and sinks. These differences cause convection currents.

How did the convection model show how Earth’s mantle moves Earth’s plates?

What happens in the circled area?
Which statement best summarizes the information in the paragraph?
How did the lab activities help you answer the lesson question: What effect does plate movement have on geologic events and structures at Earth’s surface? What did you learn from conducting this lab?
Convection currents move Earth’s plates. Plates interact with each other at plate boundaries. The interaction of plates may cause the formation of features like volcanoes that change Earth’s surface. The interaction of plates may result in geologic events like earthquakes.
