Question

how does the divergent movement of two plates affect the ocean basin between them?

Explanation:

Divergent plate movement occurs when two tectonic plates move away from each other. In an ocean - basin context, this creates a mid - ocean ridge. Magma rises from the mantle to fill the gap between the separating plates, solidifies, and forms new oceanic crust. This process widens the ocean basin over time.

Answer:

Divergent movement of two plates in an ocean basin creates a mid - ocean ridge. Magma upwells, solidifies to form new oceanic crust, and gradually widens the ocean basin.
