Chao is thinking about doing a project on plate tectonics for the school science fair. which design would best relate to how the movement in the earth’s mantle is related to plate motion?
a. a pot of boiling water to which chao will add food coloring to show the movement of the water
b. a flat shallow pan filled with a thick liquid heated by a hot plate with thick wooden blocks on top of the liquid
c. a flat shallow pan filled with small metal beads topped by an assembled puzzle that is shaken from side to side
d. a flat shallow pan filled with a thick liquid that can be heated by a hot plate with pieces of a thin plastic sheet floating on top of the liquid

I believe the answer is: D.a flat shallow pan filled with a thick liquid that can be heated by a hot plate with pieces of a thin plastic sheet floating on top of the liquid

Even though this is just a hypothesis since there no way we could actually observe the movement of earth mantle, The movement is predicted to follow these cycle: , hot water rises when heat is being applied - The hot water moves to the surface - The water spreads out and cooldown = Cooler water sinks to the bottom.

The cycle is similar to shallow pan filled with a thick liquid that can be heated by a hot plate with pieces of a thin plastic sheet floating on top of the liquid

you probably know the answer. stop asking stupid questions and making me waste my time. j.k. ; )   b.t.w. what are three ratios equivalent to 5 : 11? thx
