Science~ What moves the ocean floor and the continents?
As of now, we know that Pangea broke apart because the plates (the ocean floor) was moving. Our assignment is to theorize how the ocean floor is moving using our prior knowledge. We know that there are trenches which outline the plates/ocean floor. New rocks are formed from these trenches. Age of Rocks Map url Ocean Trench Maps url But the new rocks can't be magically appearing out of no where. There must be something that creates the rocks, in turn moving the plates and continents. My idea is that beneath the Earth's crust (first layer), the layer of magma's movement creates volcanoes. Once the volcanoes erupt, the lava cools to form the new rock. The new rock pushes away the older rocks, moving the plates/ocean floor. This movement causes the continents to move.
