What would Earth be like if our oceans never existed? That’s what Charlie wants to know! We recruit Earth detective Lucia Perez-Diaz to help us track down clues hidden within our planet’s rocks. Our investigation takes us through the mysteries of how water got on Earth, the giant plates moving beneath our feet, and why our oceans are shaped the way they are. Lucia’s also an illustrator, and will draw us an Earth without oceans. What will it look like? Listen to find out.
Learn more about how Lucia uses her detective skills to reveal the last 200 million years of Earth’s history, on our special bonus interview episode on Patreon.
