Two Minute Geology is a newish series of videos from HugeFloods.com. The Two Minute Geology videos provide short lessons on things like Ice Age floods geology, erratic boulders, and petrified wood. I've embedded the video about erratic boulders below.
Applications for Education
Two Minute Geology videos on their own certainly aren't going to replace your own lessons about geology, but they could certainly be part of flipped classroom lesson.
