Edible Tectonics
Directions: FIRST, answer question 1 – 8. The answers to these questions are found in the
BACKGROUND section of “EDIBLE TECTONICS”. .
SECOND, read the worksheet “A MOVING JIGSAW PUZZLE” and complete three
fill-in questions.
THIRD, show the teacher the work you have completed. _______________________
FOURTH, begin the lab by following the PROCEDURE in “EDIBLE TECTONICS”.
FIFTH, answer the questions under “QUESTIONS/CONCLUSIONS”.
1. Plate Tectonics is a theory that explains the distribution of _________________________
and __________________________ throughout the world. It explains how many of Earth’s surface
features such as _____________________________________________, ocean
______________________________ and fault lines were formed.
2. What layer is broken into plates?
3. Although the tectonic plates touch, do they all move together or independently from each other?
4. Do all geologists agree with the theory of plate tectonics?
5. What do many geologists think is true of the ASTHENOSPHERE?
6. What landform is created when plates move apart?
7. What landform is created when plates move together and collide?
8. What plate movement creates ocean trenches and volcanoes?
QUESTIONS/CONCLUSIONS
1. Describe the consistency (what is a made of, solid etc.) of the candy bar layers.
2. How do the layers of the candy bar compare with each other (how are they different/similar from each
other)?
3. Using the candy bar as a model for a portion of earth, what do each or the candy bar layers represent?
4. Describe what you observed when the stretched candy bar was pulled apart?
5. What might you expect to see at a point on Earth where two plates are pulled apart? (Think about
what is under the plates that are moving away from each other.)
6. Describe what you observed when the stretched candy bar was pushed together. What might you
expect to see at a point on Earth where two plates collide?
7. From what you have studied about plate tectonics so far, explain why earthquakes occur along the
boundaries (edges) of tectonic plates.
8. Earth’s mantle is composed of hot molten rock. Remember the two labs we did when you observed
convection currents in air (smoke in the convection box) and water (paper floating in a beaker of
boiling water). What might be going on in the molten mantle that would cause movement of the plates
at Earth’s surface?
