Dancing of the Continents

Through the "Dancing of the Continents" activity, I learned which continents shared things such as mountain rages and animal fossils with which continents. Before this activity, I though Pangea was shaped differently; more like a circular-looking continent, when in reality it looks more like an "L". This applies to the theory of continental drift because it discusses how the continents 'slide' over the ocean floor. The theory of sea-floor spreading states that magma oozes up between the plates, hardening and spreading them further apart, therefore moving the continents. The plates move thanks to the Theory of Plate Tectonics; the Earth's crust is broken into six large plates and many smaller ones. Scientists of different disciplines may share information such as their theories on continental drift by finding common ground in their studies and making connections between their different ideas.
