Graham Cracker Lab Plate Tectonics Activity Answer Guide

To simulate the movement of Earth’s crust, use materials like cookies and frosting to represent the different layers. Break the cookies into pieces to show how sections of the Earth’s surface shift due to external forces.

For the best results, carefully apply pressure to the edges of the cookie pieces. This will mimic how tectonic forces push and pull at different points on the Earth’s surface. By shifting the pieces toward or away from each other, you’ll visually represent how earthquakes and mountain ranges form.

Another way to visualize subduction zones is by stacking the cookie pieces. When pressure is applied, the top layer can slide over or under the other, showing the process of one plate sinking beneath another. This activity helps clarify complex geological concepts and makes it easier to understand real-world processes.

Key Takeaway: The more you manipulate the materials, the better you’ll grasp how the Earth’s surface is constantly changing. Repeating the process with different forces will help you see how various geological formations occur.
