UIView animations, are they using "Core Animation"

I'm trying to understand a basic point of the various graphics frameworks. Are UIView animations technically a feature of Core Animation or they an entirely different system? Where is the line drawn on differentiating the two?

The CoreAnimation framework sits lower than UIKit so it would probably be safe to assume that the UIKit animations are simply built from CoreAnimation animations rather than reimplementing their own animation logic. Below is the diagram from an Apple talk (Session 409 - Using the Camera with AV Foundation - 2010) to show how it's placed
