What forms earth
Evidence of the plates move
All of the continents used to be one continent called Pangea. Evidence that this is true is that all of the continents almost fit together like a puzzle. How did they move in the first place, continental drift. continental drift come in tension, compression, and shearing. There are also different boundarys. Divergent boundarys are when plates go away from each other. Convergent boundarys are when plates go towards each other. Tranform boundarys are when plates go side to side with each other.
