Which type of plate boundary is characterized by the formation of mid-ocean ridges and new oceanic lithosphere?
Answer and explanation
Correct answer: A. divergent plate boundaries
- Step 1: At divergent boundaries (e.g., Mid-Atlantic Ridge), tectonic plates move apart, allowing upwelling magma to cool and form new oceanic crust. Answer: divergent plate boundaries. Why not the others: Convergent boundaries consume crust; transform boundaries neither create nor destroy crust.
