A divergent boundary is where the two plates are moving apart. As that happens, there will be earthquakes. If it is under ocean, then sea floor will be spread and new ocean floor will be formed.
A transform boundary is where the two plates are sliding past each other. As that happens, there will again be earthquakes. The boundary becomes fault lines. I am sorry as I am not sure about the third on; it may be seafloor spreading.
that would be a primary source because it actually is his hat not a replica. a primary source is a firsthand, or the excerpt of someone who was actually there.
