Question

what type of plate boundary is seen at letter d? *

convergent (ocean crust to ocean crust)

convergent (ocean crust to continental crust)

transform

divergent

Explanation:

At a divergent plate boundary, tectonic plates move apart. Magma rises from the mantle to create new crust. In the diagram, at letter D, the ocean floor plates are moving apart, which is characteristic of a divergent boundary. Convergent boundaries involve plates coming together (either ocean - ocean or ocean - continent). Transform boundaries involve plates sliding past each other.

Answer:

Divergent
