Cross section of a divergent boundary
WebPlate interact at these boundaries. Two divergent margins (plate boundaries) are present in the cross section, one labeled as such to the right of the continental craton, and the other on the left side. The left side divergent margin is labeled Back Arc (Marginal) Basin. Back arc basins are formed by minor convection cells above subduction zones. WebThere are three types of plate boundaries: convergent, divergent, and transform boundaries. We can see the relative motion of these boundaries in cross-sections, or slices through Earth: Figure 1.

In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.
