Final answer:
Convergent boundaries can lead to the formation of island chains, rift valleys, and subduction-related volcanic activity.
Explanation:
Interaction at Convergent Boundaries
When convergent boundaries interact, various geological events can occur:
- Formation of island chains: Oceanic-oceanic convergence can lead to the creation of island arcs, which may eventually evolve into continents.
- Creation of rift valleys: Continental rift boundaries interacting with oceanic spreading ridges can result in the formation of rift valleys as the land stretches apart.
- Subduction and volcanic activity: At continent-ocean convergent boundaries, subduction occurs where oceanic plates sink beneath continental plates, leading to the formation of deep trenches, earthquakes, and volcanic activity.
