Description
The Alchemist’s Ledger: The Earth in Motion
Every map of Earth is temporary.
The Earth in Motion investigates the changing geography of the planet: continents assembling, oceans opening and closing, supercontinents forming and breaking apart, and plate tectonics reshaping the world across deep time.
From proposed early supercratons to Nuna, Rodinia, Gondwana, Pangaea, the present continental arrangement, and modeled future supercontinents, this Ledger separates observed geological evidence from reconstruction, uncertainty, and future modeling.
It is a map-heavy reference for readers who want to understand not only what scientists reconstruct, but how they reconstruct worlds whose oceans and coastlines no longer exist.
