In this final episode of Season 3, we invited Dave Chew from Trinity College Dublin, and we asked him to tell us the history of the Earth and how its appearance changed from lava ball to Snowball to what it is now. We find out how sedimentary provenance analysis and zircon help us date the build-up of past mountain chains in Ireland and in the rest of the world.
