Plate Tectonics

 To demonstrate the plate tectonics we used frosting and graham crackers. The graham crackers represent the lithosphere
1. Transform Fault- Plates slide past one another with no creation or destruction of lithosphere. I put the two graham crackers right next to one another and slid them past one another, like shown below.

2. Divergent Boundary- Two plates diverge, or move apart and new crust or lithosphere is formed. I put the graham crackers in the frosting and then pulled them apart. This is shown below.

3. Convergent Boundary- Plates converge, or come together. If a plate of oceanic lithosphere collides with thicker and less dense continental lithosphere, the denser oceanic plate will dive beneath the continent in a subduction zone. You can not use the graham crackers for this demonstration because they are stiff. A great example of convergent boundaries is when you run and jump on a carpet and the carpet hist the wall and bunches up.
