Transcript of Edible Tectonics

photo credit Nasa / Goddard Space Flight Center / Reto Stöckli By: Justin, Andy, Ravindu Edible Tectonics Apparatus Aim: To investigate plate tectonics using mars bars. 2 mars bars
paper towels Converging Plates Diverging Plates Transform Boundary Results If the Mars bar represented Earth:
The top layer represents the crust
The second caramel layer represents the mantle
The last layer represents the core

What type of plate boundary was formed when you pulled the pieces apart? If that same action happened to the plates on Earth, what would you expect to see?
It represented a diverging boundary and we would expect the tectonic plates to move apart and make more room for oceans and rivers and rifts on land. The magma will move to the surface and will harden to form land on the surface.

What type of plate boundary was formed when you pushed the pieces apart? If that same action happened to the plates on Earth, what would you expect to see?
That would be the converging plate boundary and we would expect mountains to form as the plates are pushed together or one of the plates may slide under the other one and form a volcano

What type of plate boundary was formed when you slid the pieces past each other? If that same action happened to the plates on Earth, what would you expect to see?
I think there will be an earthquake as they move along earth other

What is the force in the Earth that is moving the crustal plates along the surface?
The movement of the heated magma underneath the crust. Thanks For Watching!! :) Discussion/
Conclusion Method 1. A small Mars bar was placed on a paper towel and few cracks were scribed on top middle portion of its top with a finger-nail. 2. The Mars bar was then pulled apart slowly until the caramel started coming out. 3. The Mars bar was pushed back into together. 4. A crack was scribed using a fingernail across the middle from top through to the bottom and crack from the left to right across the middle. 5.The piece on the right hand-side of the Mars bar was pushed away whilst pulling the piece on the left hand side in the opposite direction. Continental Plate B Lithosphere Subduction Zone Volcano/Mountain Lava Lava Continental Plate A Direction of plate's motion Direction of plate's motion Continental Plate A Continental Plate B Lava Direction of plate's motion Direction of plate's motion Continental Plate A Continental Plate B Direction of plate's motion Direction of plate's motion Lava Fault Line During this experiment, we were able to explore the different kinds of layers within the Earth and the types of boundaries and transformations that occur with plate tectonics.

With the Mars bar, the outer chocolate layer would represent the crust of the earth. The caramel layer would be the mantle, and the bottom layer would be the core. With the mars bar, we could carry out several investigations that would relfect on the tectonic plates of the earth.

During part A of the experiment we observed converging and diverging tectonic plates. This is when two tectonic plates are pushed together or pulled apart.

During part B we observed a transforming boundary where two tectonic plates had moved in opposite directions to each other. They had both slid against each other in a sideways motion.

Overall it was found that Mars bars are accurate models of the different types of tectonic movements.
