Here's a breakdown:
* Transform Fault: This is the dominant type along much of the boundary, particularly in the northern section. Here, the plates slide past each other horizontally, causing earthquakes. The most prominent example is the Enriquillo-Plantain Garden Fault Zone, responsible for major earthquakes in Haiti and the Dominican Republic.
* Convergent (Subduction): In the southern section, the Caribbean Plate is subducting (diving) beneath the North American Plate. This results in volcanic activity and the formation of the Lesser Antilles island arc.
* Divergent: There are also small sections of the boundary where the plates are pulling apart, creating new ocean floor. These are often associated with volcanic activity and can be found in the eastern Caribbean.
Therefore, while the boundary is primarily characterized by a transform fault, it also exhibits convergent and divergent features. This makes it a very active and complex area, prone to earthquakes, volcanic eruptions, and other tectonic events.
