Is the Caribbean plate convergent or divergent?
convergent plate Near the eastern margin of the Caribbean plate there are recently active volcanoes in the lesser Antilles. These are associated with a convergent plate boundary and caused by subduction of the North American plate beneath the eastern edge of the Caribbean plate.
Is the Caribbean plate convergent divergent or transform?
transform plate In the Caribbean Sea, the U. S. Virgin Islands lie along a transform plate boundary where the small Caribbean Plate moves eastward past the oceanic part of the North American Plate.
