A number of triple junction diagrams are shown below. The boundaries between plates are indicated with three symbols. The lines with gray shading indicate divergent plate boundaries, the "triangle" symbol represents convergent plate boundaries and the single line with or without the "T" indicate transform plate boundaries. Your job is to determine the type of triple junction that is shown. Select the triple junction from the list. D represents divergent boundaries, C represents convergent boundaries, and T represents transform boundaries. Then select "Grade" to see if the triple junction is correct.
