Tectonic Plates Boundary One

The first place we wen to was Iceland.  I always thought it would be icy but it is green all around.  We went to the Álfagjá rift valley which is part of a boundary between Eurasian and North America Tectonic plates.  Over the boundary

 is a bridge and it was a very cool architectural design.  My friend Bobby was messing around on it and fell off into the sand below.  He broke both legs and a few ribs.  He had to get emergency evacuated in a chopper.  While this set us back it didn't stop us from learning.  What was going on with the plates on this boundary is shown in picture on the bottom;  The divergent plate boundary is when the plates slide away from each other.
