6: Working Out the Core

This podcast starts at the beginning of Earth's prehistory and works forward through time.  Bedrock will explore the first 90% of Earth’s past, a time known as the Precambrian Era.  Before humans, before dinosaurs… there was the Precambrian.
The Earth was an incredibly alien world, but not a dead one. 
Along the way, you will build a mental toolkit to see the world like a geologist. You will never look at a mountain, the moon, or pond scum in quite the same way again.

Welcome to Bedrock.
