Dance of the Continents

• The theory of Continental Drift states that the continents were once a single landmass that drifted apart and are still doing so. 
• The theory of Sea Floor Spreading is  the process by which new oceanic crust is formed by the convective up-welling of magma at mid-ocean ridges, resulting in the continuous lateral displacement of existing oceanic crust. 
• Theory of plate tectonics- holds that the entire crust of the earth is broken into six large pieces (plates) and many smaller ones, that any plate may consist, in part, of ocean floor and, in part, of a continent or islands.

• I learned that the continents spread apart and move, Example of continental drift. They will continue to move around and eventually look completely different. 
• Scientist share information in many different ways.  Most of them record journals to keep all of their data in.
