Plate Tectonics Oreos🍪🌎

      In science we have been learning about the Plate Tectonics. We did an activity to represent the Plate Tectonics, for that we used an Oreo. We did this so we could have a safe visual of what we might see when the Plates move or slid past each other. I enjoyed this activity because it was a fun way to learn what would actually happen in real life, if we saw a plate tectonic movement. I especially enjoyed it because we got to use one of my favorite treated Oreo's. 

      Each layer of the cookie means a layer of the earth for example the top part of the Oreo is the Crust the (Lithosphere), the white part is the mantle the (Asthenosphere), and the bottom part of the Oreo represented the lower mantel. The Oreo was a good representations of the earth because it had a clear view of the plates and it was a good way to represent a model of the plate boundaries. 

    When the cookies were pulled apart you can see a crack open up between both plates. In real life when to plates moved apart if it was in the oven then lava will erupt and then cool down and harden, that will make an new Oceanic crust. You may also see some rifts valleys, (rift valleys) are low places on the plate just like the one I labeld below. Hills are high places on a plate, and lastly crackmare small open parts. This is called a Divergent Boundary.

      When the stretched cookie was pushed together. The denser plates would sinks below the much stronger plate, another word for this is (subduction). If this was to,happen in real life then you maight expect a tsunami, and it can also form a line of volcanoes or an earthquake. This is an Convergent Boundary Plate. In a covergent plate boundary you may expect to see some valleys, hills and cracks. The two types of convergent plates are the ocean-to-continent that's when the much lighter plate sinks below the stronger plate. The second type of convergent plate is continent-to-continent that's when plates that are the same density push together, this will form a big mess of rocks, and force of to plates pushing and starting to rise, this also creates mountains jut like the Himalayas in India.

When the snicker bar slid past another snicker bar. This in real life can cause a very fast shift in the land, just like what happened in Nepal. Because the two plates are using a lot of energy to move past eachother the plates may get stuck and stop moving. You may expect to see some cracks (faults), and hills. This plate is called a Transform plate. 

Some of the questions I still have is. Are we the only planet in our Solar System that has Plates? How wear plate Tectonics discovered? Would Earth be different if we didn't have any Plate tectonics? If we didn't have plates would volcanoes not exist?
