Transitions in sentences create internal coherence, while transitions between paragraphs create coherence?

I believe the answer is external coherence.

I know no other answer than external. It is the most sensible.

Internal coherence is important to be sure that the story makes sense and can be run in isolation. External coherence is how it relates into the wider narrative of change and the world around us.

Hope that helps!
