Journal 2-Conclusion to prac 2

Today we modeled the mid-ocean spreading of tectonic plates.We pushed paper out of a small gap out between two tables . The paper represented the ocean floor and bulges of the paper were the lava flow convection currents pushing the paper up. We measured this because the force pushing the paper up was our hands and is in reality the lava flow, but as the paper grew higher in length from the middle, that was the mid ocean ridge across the ocean floor.
