Sometimes a cave is just a cave. Geologist Marcia Bjornerud will give us a guided tour of Plato's Cave.

Videos that capture thinking on geologic timescales, provided by Marcia:
Nice illustration of how scale modeling with sand can allow us to see mountain-building processes too slow to experience directly: https://www.youtube.com/watch?v=d9bKXY0OMxc
This one is not about rock deformation over time, but shows how geologists take 2D surface (map) information and convert it into 3D: https://www.youtube.com/watch?v=5CHd6_cIT44
A recently released depiction of plate motions over the past 800 million years: https://www.nytimes.com/2021/02/06/science/tectonic-plates-continental-drift.html
A more detailed plate tectonics animation centered on the Mediterranean region over the past 200 millions years (it first goes backward in time, then forward again to the present): https://www.facebook.com/GeologyWay/videos/2576386299268336/
But Marcia's absolute favorite is this non-scientific animation: "Das Rad/The Rocks": https://www.youtube.com/watch?v=HOPwXNFU7oU
I hope you enjoy our discussion!
