Episode notes
Earth's Remarkable Archive
- Earth's crust holds a unique, accessible record of its history, unlike other planets.
- This 'rock record' compresses billions of years of events into the present-day continents.

- Having access to Earth's nearly complete history is unusual among planets.
- Rocks should be viewed as verbs, signifying ongoing planetary processes, not static nouns.

- Earth’s dynamic processes both create and destroy rocks, creating a paradox for preserving history.
- Venus, for example, seems to have erased its early history with volcanic activity.
