Plate Tectonics

~The lithosphere is broken into seven major pieces called plates
~Shows how the Earth works in the form of geology

~The plates meet at places called plate boundaries
~Can cause earthquakes, the formation of mountains, and volcanoes due to the way they collide
~Alfred Wegener was the first to realize that the continents seemed to fit together like puzzle pieces
~Scientists eventually discovered that the mantle undergoes convection and the heating and cooling causes plates to move
