=Plate Tectonics=

Millions of years ago, the continents were smashed together into one big land mass.



What made them move apart, like they are today? Let's think about this crowd of people. They're all close together, and can't move around very much. But what if something started to draw certain groups into other areas? Maybe Metallica is playing on one side of this festival, Rhianna in another area, and Itzhak Perlman in yet another (never mind what kind of crazy concert this is!). The crowd will begin to disperse. They are being drawn away (by the music) but also pushed away (by other people in the crowd).



This movement won't happen without some accidents happening. If Rhianna goes down into the crowd, some people might get trampled trying to get close to her (like convergent boundaries). If someone gets drawn by the crowd to Metallica when he really wanted Perlman, this is like divergent boundaries. And some people might get pushed as they pass in opposite directions (transform boundaries).
