- 10. Multiple Choice
What effect might tectonic plate movement have on the size of an ocean basin?
An ocean basin becomes larger when new crust is created at transform boundaries.
An ocean basin becomes larger when new crust is created at convergent boundaries.
There is no effect on the size of an ocean basin because it is below sea level.
There is no effect on the size of an ocean basin because crust is created at divergent boundaries and destroyed at subduction zones.
